I created a cluster successfully and then deleted it.
Now when I try to create a new cluster. After I have chosen all the roles and hosts, it fails at the 3rd step where it is trying to format the name node.
so it seems the data from the previous cluster is already there and that is why the new one is not able to format it.
Now do I remove old data?
I figured out. there is a directory called /dfs
I deleted this directory on each machine and then retried. it worked perfectly
