Task 11.1
Creating hadoop cluster using ansible playbook!
Steps to follow-
1 Check prerequisites-
This includes installing ansible using (pip3 install ansible) and adding IP’s of namenode and datanode to the inventory. Checking the connection using ansible ping command.
2 Creating playbook-
You have to create 2 playbooks, one for datanode and one for namenode, the playbooks are basically the same for both the nodes.
This is the basic playbook for both nodes just you need to change the path for different nodes as in the creating a folder using the root storage, basically replace namenode with datanode in the playbook.
3 Running the playbook-
Command is “ansible-playbook <filename.yml>”
Similarly playbook of datanode ran successfully.
4 Double check!
