In this blog you will see how the configuration the Hadoop cluster by the Ansible.
Let’s See First what is ansible and Hadoop.
What is Hadoop?
Hadoop is an open source, a Java-based programming framework that supports the storage and processing of extremely large data sets in a distributed computing environment. It is part of the Apache project sponsored by the Apache Software Foundation.
What is Ansible?
Ansible is an open-source software that automates software provisioning, configuration management, and application deployment.
Now Let’s start practical :
Steps To configuratio Hadoop by ansible …
Step 1: Copying the hadoop software
Step 2: Copying the java software
Step 3: Installing thee hadoop software
Step 4: Installing the java Softwrae
Step 5: Create the Directory
Step 6:Configuration the core-site.xml
step 7: Cofiguration the hdfs-site.xml
Step 8: Start datanode or namenode if namenode then format
First write inventory :
Now Cofiguration in Namenode by hadoop.yml
hadoop.yml for Namenode
namenode ip is 192.168.0.113
datanode ip is 192.168.0.108
Namenode Confi.. : yml File..
So now our Namenode is started.. see by ‘jps’ command
Now Configuration in Datanode
hadoop2.yml for Datanode
Datanode Confi .. yml File :
So now Our datnode is started succesfully , see by ‘jps ’ command
Now you can confirm by Type url:192.168.0.113:50070
