Suggested December 2023 Hbase Query Example: Put(), Get(), Scan() Command In Hbase

In this tutorial, you will learn:

Write Data to HBase Table: Shell

The put command is used to store data into a table

This command is used for the following things

It will put a cell ‘value’ at a defined or specified table or row or column.

It will optionally coordinate time stamp.

Example:

Here we are placing values into table “guru99” under row r1 and column c1

We have placed three values, 10,15 and 30 in table “guru99” as shown in the screenshot below

Suppose if the table “Guru99” having some table reference like say g. We can also run the command on table reference also like

The output will be as shown in the above screenshot after placing values into “guru99”.

Read Data from HBase Table: Shell

In this section, we will check the following

Values that are inserted into HBase table “guru99”

Column names with values present in HBase Table guru99

From the above screenshot, we can infer

If we run “scan” command in HBase shell it will display the inserted values in “guru99” as follow

In HBase shell, it will display values inserted by our code with column and row names

Here we can see the column name inserted are “education” and “projects”

The values inserted are “BigData” and “HBase Tutorials” into mentioned columns

You can also use the Get command to read data from a table

By using this command, you will get a row or cell contents present in the table. In addition to that you can also add additional parameters to it like TIMESTAMP, TIMERANGE,VERSIONS, FILTERS, etc. to get a particular row or cell content.

Examples:-

For table “guru99′ row r1 and column c1 values will display using this command as shown in the above screenshot

For table “guru99” row r1 values will be displayed using this command

For table “guru99” row 1 values in the time range ts1 and ts2 will be displayed using this command

For table “guru99” row r1 and column families’ c1, c2, c3 values will be displayed using this command

Write Data to HBase Table: JAVA API

In this step, we are going to write data into HBase table “guru99”

First, we have to write code for insert and retrieve values from HBase by using-HBaseLoading.java program.

For creating and inserting values into a table at the column level, you have to code like below.

From the above screen shot

When we create HBase configuration, it will point to whatever the configurations we set in chúng tôi and chúng tôi files during HBase installations

Creation of table “guru99” using HTable method

Adding row1 to table “guru99”

Specifying column names “education” and “projects” and inserting values into column names in the respective row1. The values inserted here are “BigData” and “HBaseTutorials”.

Read Data from HBase Table: Java API

Whatever the values that we placed in HBase tables in the above section, here we are going to fetch and display those values.

For retrieving results stored in “guru99”

The above screenshot shows the data is being read from HBase table ‘guru99’

In this, we are going to fetch the values that are stored in column families i.e “education” and “projects”

Using “get” command we are going to fetch stored values in HBase table

Scanning results using “scan” command. The values that are stored in row1 it will display on the console.

Once writing code is done, you have to run java application like this

After running “HBaseLoading .java” the values going to insert into “guru99” in each column in HBase and in the same program it can retrieve values also.

Here is the complete code

import java.io.IOException; import org.apache.hadoop.hbase.HBaseConfiguration; import org.apache.hadoop.hbase.client.Get; import org.apache.hadoop.hbase.client.HTable; import org.apache.hadoop.hbase.client.Put; import org.apache.hadoop.hbase.client.Result; import org.apache.hadoop.hbase.client.ResultScanner; import org.apache.hadoop.hbase.client.Scan; import org.apache.hadoop.hbase.util.Bytes; public class HBaseLoading { public static void main(String[] args) throws IOException { org.apache.hadoop.conf.Configuration config = HBaseConfiguration.create(); /*This instantiates an HTable object that connects you to the "test" table*/ HTable table = new HTable(config, "guru99"); /* To add to a row, use Put. A Put constructor takes the name of the row you want to insert into as a byte array.*/ Put p = new Put(Bytes.toBytes("row1")); /*To set the value you'd like to update in the row 'row1', specify the column family, column qualifier, and value of the table cell you'd like to update. The column family must already exist in your table schema. The qualifier can be anything.*/ p.add(Bytes.toBytes("education"), Bytes.toBytes("col1"),Bytes.toBytes("BigData")); p.add(Bytes.toBytes("projects"),Bytes.toBytes("col2"),Bytes.toBytes("HBaseTutorials")); table.put(p); Get g = new Get(Bytes.toBytes("row1")); Result r = table.get(g); byte [] value = r.getValue(Bytes.toBytes("education"),Bytes.toBytes("col1")); byte [] value1 = r.getValue(Bytes.toBytes("projects"),Bytes.toBytes("col2")); String valueStr = Bytes.toString(value); String valueStr1 = Bytes.toString(value1); System.out.println("GET: " +"education: "+ valueStr+"projects: "+valueStr1); Scan s = new Scan(); s.addColumn(Bytes.toBytes("education"), Bytes.toBytes("col1")); s.addColumn(Bytes.toBytes("projects"), Bytes.toBytes("col2")); ResultScanner scanner = table.getScanner(s); try { for (Result rr = scanner.next(); rr != null; rr = scanner.next()) { System.out.println("Found row : " + rr); } } finally { scanner.close(); } } } Summary:

As we discussed in this tutorial, you can use the put command to insert data into a table. You can use the scan, get command to read data from a table

How To Remove Query Strings In WordPress? – Webnots

WordPress is a content management system that helps to assemble various resources and present a beautiful layout in the browser. It needs core WordPress software, theme and plugins to make a simple WordPress website. These items in turn contains source HTML, PHP, CSS and JavaScript files. Developers used to maintain versioning of these source files by adding a query string at the end of the URL. Though it helps developers, it can create lot of problems for website owners in terms of speed and security. In this article, we will explore what are query strings in detail, how it can impact your site and how to remove query string in WordPress.     

Where are Query Strings Used?

Query strings are used in two major ways – frontend and backend.

Frontend – you can find query strings in ecommerce websites like Amazon for searching products. Similarly, WordPress forum websites use query string to serve dynamic content for particular user session.

Backend – theme and plugin developers in WordPress use query strings in CSS and JS files for versioning. For example, if you Jetpack plugin version 10, the related CSS and JS files loading in the backend will have query strings after the URLs like /?v=10.0.

Frontend – Using Query Strings Dynamically with Slug

A standard post or page URL in WordPress contains domain name and slug like below:

However, you can append some additional parameters in the URL after a question mark symbol in URL. For example, the below URL will search the given string in WordPress site and show the results.

These parameters are called query strings and is possible to use multiple parameters in single URL for getting desired results. Below is the pictorial representation of how a query string in a WordPress URL will look like.

Query Strings Format

Generally, using query string with slug is needed to achieve functions like searching using default WordPress search, product searches in ecommerce websites and serving dynamic content in forum websites. We are not discussing use of query strings dynamically with slug in this article.

Backend – Using Query Strings with Static Resources

As mentioned, developers use query strings to keep track of the changes and release new version of the plugin or theme. You can easily view query strings in CSS and JS by looking at the source code of your WordPress site.

Query Strings in CSS and JS Files

As you can see the CSS and JS files are having version number at the end which are the query strings. In this article, we primarily discuss the query strings used in the backend CSS and JS files.

Why You Should Remove Query Strings in WordPress?

Though query strings are useful for developers, you will have the following problems:

Earlier days browsers were not caching static files with query string in the URL. Due to this fact, each time these files are requested from origin web server causing delay in page loading speed. That time, remove query strings was one of the problems you would frequently see in Google PageSpeed Insights and other speed measurement tools. However, Google Chrome and other browsers will cache based on the cache header present on the website and follow query strings. We still recommend removing query strings since some CDN and proxy servers can’t cache file URLs with query strings.

Besides caching, these query strings can be vulnerable to security attacks, enabling hackers to gather sensitive information such as login credentials, tokens, database details, and much more. For example, a plugin installed on your site might had a security problem. The developer released a new version to patch up the issue and disclosed the details publicly on their site. If you did not immediately update the plugin, any hacker can view the source code of your site and understand you are still using the old plugin version from the query strings of CSS and JS files.

Removing query strings mitigates such vulnerabilities and enables browser caching of static files. This will protect as well as improve the performance of your website. Since page speed is a critical for good ranking in Google, you should remove the query strings from statis files on your WordPress site.

How to Remove Query Strings in WordPress?

In this article, we will look at few different ways to remove query strings in WordPress:

Remove query strings with a plugin

Manually remove query strings without a plugin

Remove Query Strings with Plugin

There are several free plugins you can use to remove query strings in WordPress. These plugins can also help to speed up your site by performing a variety of activities. Some of the most popular plugins include:

W3 Total Cache

WP Performance Score Booster

Hummingbird Plugin

Using SG Optimizer for SiteGround users

1. Remove Query Strings with W3 Total Cache

W3 Total Cache plugin is a free tool for caching websites and reducing site loading time. The plugin also provides a query string removal option for WordPress.

Note: As mentioned, modern browsers and page speed testing tools do not work based on query strings. Hence, many premium plugins like WP Rocket and Perfmatters removed the option for removing query string from static resource.

Manually Remove Query Strings with Code

Alternatively, if you don’t want to use any additional plugins on your website, you can opt to remove query strings manually using a PHP code. You can insert a code block in your theme’s chúng tôi file to achieve this.

Edit Functions

Paste the code below at the bottom of the file.

function removeQueryStrings( $src ) {  if( strpos( $src, '?ver=' ) )  $src = remove_query_arg( 'ver', $src );  return $src; } add_filter( 'style_loader_src', 'removeQueryStrings', 10, 2 ); add_filter( 'script_loader_src', 'removeQueryStrings', 10, 2 );

This method can be tricky at times as you might easily break your website. Though you can child theme, we recommend using “Code Snippets” plugin instead of editing chúng tôi file.

Add Code with Code Snippets Plugin

To get started, install and activate the Code Snippets plugin.

Locate the “Snippets” menu and select “Add New” to add a new snippet.

Add Code Snippet

On the window that appears, enter the title of new snippet and paste the code above in the “code section”. You can as well add a description if you like.

Whether you use a plugin or manually inserting the code, make sure to clear your cache and test the page. You should not see any CSS and JS file URLs with version number in the source code.

Conclusion

Query strings can be useful for development purposes to maintain versioning. However, some servers can’t cache the files with query string and they can also be a security issue. If you want a quick and straightforward method, use any of the plugins listed above. Alternatively, you can use the code provided with or without a plugin.

Does Ios 15 Scan Photos?

Like every year, like clockwork, a new version of iOS has dropped. The latest, iOS 15, not only improves some of iOS 14’s staple features but also brings a bunch of new stuff. As always, there has been some controversy surrounding the new OS. This time, it comes in the form of Child Safety. This new addition practically makes way for Apple to scan photos in your gallery, which has ruffled quite a few feathers in the industry. 

Today, we will tell you how this technology works and tell you whether Apple’s iOS 15 scans your private photos.

Will iOS 15 scan photos in your gallery?

Child Safety in iOS 15 is a newly introduced feature that is meant to stop the distribution of Child Sexual Abuse Material or CSAM. To make it work, all iOS 15-running devices does scan for problematic content on every user’s device and notify the authority if necessary. So, technically, yes, iOS 15 does scan your photos under certain circumstances.

However, the situation, at least from Apple’s perspective, is a lot less dire than most are making out to be. Instead, Apple believes its CSAM scanning is a lot more secure than the techniques its competitors are using.

How does photo scanning work in iOS 15?

If you go by the sensationalized reports, you would think that Apple employees might actually be looking into your private photos one by one. Yes, we understand that these wild reports originated from Apple’s overly simplistic feature announcement, but the company has since gone on and added more clarity to the Child Safety tech or CSAM scanning. 

The downloaded database is converted into string (of numbers) format, which means the users are not seeing the images on their iPhones. If a match is found, National Center for Missing and Exploited Children (NCMEC) gets notified, and then a human reviews the matches personally. Finally, if the representative finds the image problematic, appropriate actions are taken against the perpetrator. 

Apple’s clarification confirms that no human Apple employee scans and reviews your photos, at least right away. The NCMEC database is the first layer of verification. If and only if a match is found, the photo is sent over to NCMEC where it is verified by a human.

Can you stop iOS 15 from scanning your photos?

Yes, stopping iOS 15 from scanning your photos is rather straightforward. All you have to do is stop uploading your photos to iCloud and you are good to go. Apple has confirmed that the check is performed only if you have opted to upload your photos to iCloud. In 2023, iCloud has over 170 million premium users, meaning a sizable chunk of the smartphone population is affected by the CSAM scanning functionality.

Is iOS 15 comprising your privacy? 

Unlike other services that scan your entire library, Apple promises that it only matches your library with the on-device CSAM database, instead of scanning your entire iCloud library. If a match is found, then only your photo leaves your device and is viewable by another human. Also, Apple is making the CSAM databases auditable, hoping to put most of the doubters’ minds at ease.

Many still believe that governments could use iOS 15’s CSAM scanning as a backdoor to look for wanted fugitives, target certain demographics, and more. Apple has reassured that iOS 15’s image scanning is only built for CSAM databases and cannot be configured otherwise. 

Apple has landed itself in a tough spot with CSAM scanning, and it is anybody’s guess whether the most valuable company in the world would be able to get out of it.

How Did Requests Work In Jsp With Example?

Introduction to JSP request

Web development, programming languages, Software testing & others

Parameter passing.

To retrieve the server name, server address, server port, and other server related information.

To retrieve remote addresses of web pages over the network.

To get, set, or delete multiple attributes during the website run.

To pass information from one page to another via jsp pages using variables.

So JSP requests are one of the major sources of data exchange over the web. We will understand more about this topic with the help of syntax and examples provided below.

Syntax

The syntax used for JSP requests to function is given here. It uses the keyword “request” along with the attribute “getParameter”. The string which is to be stored under the variable “StringName” is passed as a parameter to it in the format below.

String StringName=request.getParameter("Name"); How did requests work in JSP?

JSP requests use some of the core implicit attributes from the HttpServletRequest object to pass the data further as the user progresses in a web search or website exploration. One of the easiest examples to understand is when we log in to any webpage, and we see “welcome userName” on the page as soon as we login. The “userName” is replaced dynamically as per the user who logged in.

IT is different and unique for all users. So here, “JSP request” is used to fetch the user name as per the login details entered by the user. The “Request” object by JSP keeps track of recorded information and responses as per the entered information. This is essential to make the page dynamic and responsive as per the user query.

Example of JSP request

Let’s look into one example, which is followed by an explanation for a better understanding of the concept.

JSPRequest2.jsp :

<% String Username=request.getParameter(“name”); int letter_count=obj.countcalculate(Username); out.print(“The number of letters containing in the string is “);

<%@ page language="java" contentType="text/html; charset=UTF-8"

CountCalculator.java :

package test1JSP; public class CountCalculator { public int countcalculate(String name) { String str = name; int count = 0; for (int i = 0; i < str.length(); i++) { if (Character.isLetter(str.charAt(i))) count++; } return count; } }

Output:

Explanation: This is an example; three files are used to explain how the request parameter is used in the file coming from the remote file. Three files used in this sequence:

3. java: This is an intermediary page with the business logic. In this example, we wanted to calculate the number of letters passed in the string on the landing page. The logic to calculate the number of letters in the string is written here. The if the loop is used to iterate and check each letter of the string. “Character.isLetter(str.charAt(i))” is used to check if the letter at particular iteration is a character or not. If it is a character, then the count is added with 1 each time. Suppose northern count is not added with 1 and remains as it is. This loop is terminated once it reaches the end of the string passed. Finally, an integer count is returned from this java program enabled by function countcalculate to be printed over the screen.

The JAVA file string which is passed from the landing page should again be declared as “name” so that there is no discrepancy in understanding how data flowed from the landing page to the final page. The data flow is:

Conclusion

The JSP requests are used as an important tool for passing data values and other important information from one page to another. This enables easy transition of data flow on the web. Many attributes can be used along with request objects to fully use this functionality incorporated under JSP pages.

How Does Property Work In Jsp With Example?

Introduction to JSP property

Web development, programming languages, Software testing & others

Syntax

The syntax used by the JSP property is :

<jsp:setProperty name="Name_to_identify_bean" <jsp:getProperty name="Name_to_identify_bean" <jsp:useBean

The “setProperty” or “getProperty” after colon JSP is the identifier for the compiler. By this compiler identifies that the property functionality of JSP has been used. “Name” tag is used to set the name to identify the JAVA bean, which will carry the property name along with values. “Property” is used to assign property names.

The useBean tag mentioned in the end is used to locate the remotely located bean, which can then be used for processing of JAVA beans. Note here that “name” on property and “id” in usebean JSP tags should be the same.

How does property work in JSP?

Name: This is a mandatory attribute. This attribute is used to identify the EJB. Refer to syntax carefully as this name should match to JSPBean’s name.

Property: This is a mandatory attribute. This defines which properties should be set. For example, if “*” is given as a value for this parameter, then all the properties are set as per the setter method in EJB.

Param: This attribute is optional. This attribute is equal to the request parameter name. This parameter is getting the incoming value that would be assigned to the property. “Param” and “Value” can not be used together as both of these attributes are used to assign value to the property in the tag itself, although the method of assigning values is different.

Value: This attribute is optional. This attribute is used to set a value to the property in the tag itself rather than fetching it from some other place. If this attribute is not present or the value is zero, then the “setProperty” property is being ignored by the compiler.

EJB: A JAVA bean should be defined with getting and set methods that would take the property values fetched from property tags and then assign them to the variables. These variables are sent again wherever required. We can understand more about its working with the help of an example provided in the below section.

Examples of JSP property

This is an example where we will create an index page with a form that collects email id, name, and password and then finally displays it in the output by carrying the user input name, password and email via properties. There are some files to be created to accomplish the task.

File: Index.html

File: Test1.java package test1JSP; public class Test1 { private String n,p,e; public String getName() { return n; } public void setName(String name) { this.n = name; } public String getPassword() { return p; } public void setPassword(String password) { this.p = password; } public String getEmail() { return e; } public void setEmail(String email) { this.e = email; } } File: Test1.Class / Compiled from chúng tôi (version 12 : 56.0, super bit) public class test1JSP.Test1 { private java.lang.String n; private java.lang.String p; private java.lang.String e; public Test1(); 0  aload_0 [this] 1  invokespecial java.lang.Object() [12] 4  return Line numbers: [pc: 0, line: 3] Local variable table: [pc: 0, pc: 5] local: this index: 0 type: test1JSP.Test1 File: useBean2.jsp

Output:

Explanation:

In this example, three files are created named “Index.html”, “useBean2.jsp” and “Test1.java”. “Index.html” is simply the web page to input the values. Here the form is used to collect the details required. The “action” attribute in the form tag links this static HTML page to the dynamic JSP page named “useBean2.jsp”. This JSP page sets the property with the help of JSP property tags. One thing to notice here is that there is a “useBean” tag also defined on the JSP page, which establishes a link between the JSP page and the JAVA class. The name of the properties, the id of useBean tag is the same, which is “u”. “setProperty” sets all the properties with the value fetched from the HTML page and “getProperty” gets the value which is set via the “setProperty” tag. In the background, the JSP bean connects with the JAVA class page “Test1.java” and uses get and set methods to set the values. Get the method to fetch the value and displays it on the output screen.

Conclusion

JSP property is used commonly to streamline the data flow between multiple pages in the backend when we run any web application. In addition, it helps in enhancing user interactive sessions by the use of dynamic web content loading. One of the most useful tools for front end developers.
