Ansible configuration file:

Ansible hosts file:

Now that we have configured our ansible inventory and hosts file, we can ping the hosts and check whether they are connecting or not in the following way:

Namenode setup:

Ansible-playbook namenode.yml
(P.S: the error in task[installing jdk software] is because I have already installed jdk software in my system. And this error is being ignored so it wont effect other process)

Run the “jps” command to check whether the Hadoop namenode has started or not,

Datanode setup:

Ansible-playbook datanode.yml
(P.S: the error in task[installing jdk software] is because I have already installed jdk software in my system. And this error is being ignored so it wont effect other process)

Run the “jps” command to check whether the Hadoop datanode has started or not,

Access the below mentioned GitHub link to checkout the “namenode.yml” and “datanode.yml” files.
