Implement Kerberos authentication in Hadoop

Kerberos is a network authentication protocol that can be used to secure Hadoop clusters. Here are the basic steps to implement Kerberos authentication in Hadoop:

  1. Install and configure a Kerberos server: This will typically involve installing the Kerberos software on a separate server, configuring the Kerberos server's settings and creating the necessary user accounts and credentials.

  2. Configure Hadoop to use Kerberos: This will involve modifying the Hadoop configuration files (such as core-site.xml, hdfs-site.xml, etc) to set up the necessary properties for Kerberos authentication. For example, you will need to set the following properties:

<property>
  <name>hadoop.security.authentication</name>
  <value>kerberos</value>
</property>
<property>
  <name>hadoop.security.authorization</name>
  <value>true</value>
</property>

  1. Generate keytab files: For each service that needs to authenticate using Kerberos (such as the Namenode, Datanode, Yarn Resource Manager, etc), you will need to generate keytab files containing the necessary Kerberos credentials.

  2. Start Hadoop daemons with the appropriate keytab files: This can be done by setting the appropriate environment variables and/or command-line arguments when starting the Hadoop daemons.

  3. Create a principals for the all Hadoop services and users: The principals need to be created in the Kerberos server.

  4. Test the configuration: To test the configuration, you can use the kinit command to authenticate as a user and check that you are able to access the Hadoop services.

It's worth noting that Kerberos authentication can be somewhat complex to set up, and it is recommended to work with an expert in your organization or consult the official documentation from Apache Hadoop to ensure that your configuration is done correctly. Also, security configurations may vary depending on the version of Hadoop you have. 


Sure, here is an example of how you might configure Kerberos authentication in a Hadoop cluster:

  1. Install and configure a Kerberos KDC. For this example, we'll assume that you're using MIT Kerberos, which is one of the most commonly used Kerberos implementations. You can install it on a separate server using your operating system's package manager. Once it's installed, you'll need to configure the KDC by editing the /etc/krb5.conf file to specify the location of the KDC and the Kerberos realm.

  2. Create principals for the Hadoop services and for the users that will be accessing the services. For example, to create a principal for the HDFS service, you might run the following command:

$ kadmin.local -q "addprinc -randkey hdfs/hadoop-server.example.com@EXAMPLE.COM"

Here, hdfs/hadoop-server.example.com is the principal name and EXAMPLE.COM is the Kerberos realm. Repeat the process for other services and users

  1. Add the Kerberos-related configuration settings to the core-site.xml, hdfs-site.xml, and yarn-site.xml configuration files. For example, in core-site.xml you need to add:
<property>
  <name>hadoop.security.authentication</name>
  <value>kerberos</value>
</property>
<property>
  <name>hadoop.security.authorization</name>
  <value>true</value>
</property>
<property>
  <name>hadoop.security.auth_to_local</name>
  <value>RULE:[1:$1@$0](.*@EXAMPLE\.COM)s/@.*//</value>
</property>
  1. Create keytab files for the Hadoop services and for the users that will be accessing the services. You can use the ktutil command to create a keytab file for a principal. For example, to create a keytab file for the HDFS service, you might run the following command:
$ kadmin.local -q "ktadd -k /etc/hadoop/conf/hdfs.keytab hdfs/hadoop-server.example.com@EXAMPLE.COM"
  1. Start the Hadoop services, such as HDFS and YARN, and configure them to use the keytab files that you created in step 4. You can do this by specifying the keytab file location in the appropriate configuration file (e.g hdfs-site.xml or yarn-site.xml). For example, in hdfs-site.xml :
<property>
    <name>dfs.web.authentication.kerberos.keytab</name>
    <value>/etc/hadoop/conf/hdfs.keytab</value>
</property>
<property>
    <name>dfs.web.authentication.kerberos.principal</name>
    <value>hdfs/hadoop-server.example.com@EXAMPLE.COM</value>
</property>

Python script that you can use to test the speed of an SCP (Secure Copy Protocol) transfer

 import time import subprocess start_time = time.time() # Replace [source] and [destination] with the file paths you want to use subprocess.run(["scp", "[source]", "[destination]"]) end_time = time.time() transfer_time = end_time - start_time print(f"Transfer time: {transfer_time} seconds") This script will start a timer, run the scp command to transfer a file from the source to the destination, and then stop the timer. It will then print out the total transfer time in seconds. You can modify this script to fit your specific needs. For example, you might want to specify additional options for the scp command, or you might want to run the transfer multiple times and average the results. To measure the speed of an SCP (Secure Copy Protocol) transfer, you can use the following Python code import time import subprocess # Replace [source] and [destination] with the file paths you want to use subprocess.run(["scp", "-v", "[so...

Hive commands with examples

Here are some common Hive commands with examples: CREATE TABLE - creates a new table in the Hive warehouse. Example: CREATE TABLE employees ( name STRING, age INT , city STRING, salary FLOAT ) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' ; LOAD DATA - loads data from a file in the local file system or a remote location into a table in the Hive warehouse. Example: LOAD DATA LOCAL INPATH '/path/to/local/file.txt' INTO TABLE employees; SELECT - retrieves data from a table in the Hive warehouse. Example: SELECT * FROM employees WHERE salary > 50000 ; INSERT INTO - inserts data into a table in the Hive warehouse. Example: INSERT INTO TABLE employees VALUES ( 'John' , 30 , 'New York' , 60000 ), ( 'Jane' , 25 , 'Chicago' , 50000 ); UPDATE - updates data in a table in the Hive warehouse. Example: UPDATE employees SET salary = 55000 WHERE name = 'Jane' ; DEL...

Copy data from a local file system to a remote HDFS file system using Apache NiFi

 To copy data from a local file system to a remote HDFS file system using Apache NiFi, you can use the PutHDFS processor. This processor allows you to specify the remote HDFS file system location to which you want to copy the data, as well as any configuration properties needed to connect to the HDFS cluster. Here is an example template that demonstrates how to use the PutHDFS processor to copy data from a local file system to a remote HDFS file system: Drag and drop a GenerateFlowFile processor onto the canvas. Configure the GenerateFlowFile processor to generate a flow file that contains the data you want to copy to HDFS. Drag and drop a PutHDFS processor onto the canvas, and connect it to the GenerateFlowFile processor using a connection. Double-click the PutHDFS processor to open its properties. In the HDFS Configuration Resources property, specify the HDFS configuration resources (e.g. core-site.xml , hdfs-site.xml ) needed to connect to the remote HDFS cluster. In the...

Kubernetes Deployment rollout

 In Kubernetes, you can use a Deployment to rollout new updates to your application. A Deployment is a higher-level object that manages a set of replicas of your application, and provides declarative updates to those replicas. To rollout a new update to your application using a Deployment , you can update the Deployment configuration to specify the new version of your application. The Deployment will then rollout the update to the replicas in a controlled manner, according to the update strategy specified in the Deployment configuration. For example, you can update the Deployment configuration to specify a new container image for your application, like this: apiVersion: apps/v1 kind: Deployment metadata: name: my-deployment spec: replicas: 3 selector: matchLabels: app: my-app template: metadata: labels: app: my-app spec: containers: - name: my-app image: my-app:v2 This Deployment configurat...
