I am testing swapping of 3 nodes in a cluster with 3 new nodes without data loss.I am done with all the steps.
I have decommisioned the old nodes and i am able to see data in the volumes is intact when i check from mcs.
However when I try to run hadoop fs -ls / command. I get the following error.
[mapr@psnode149 ~]$ hadoop fs -ls /
