Vinayakumar B commented on HDFS-9337:
-------------------------------------
Thanks for the patch [~jagadesh.kiran] and Thanks [~walter.k.su] for review.
I see that HDFS-9338 also to validate another op.
I feel it would be better to add a generic method to verify required params for
a given op. and call that method with necessary params in one Jira.
[~walter.k.su], Do you agree?
