Brahma Reddy Battula commented on HDFS-13998:
---------------------------------------------
IMHO, HDFS-13732 change might not require..? As admin will be aware of
configured policy and these are admin commands.
Adding RPC can mislead
For concurrent calls and any error while getting the policy after setting.
and Extra overhead as [~ayushtkn] mentioned.
Audit log ( for debugging) and RPC call
If you all agree, we should revert HDFS-13732 before we ship 3.2 release and
Follow up for next release..?
If we really required why can't we do through getserverdefaults()(by adding EC
field there).

> This jira is to fix it in ECAdmin, and add a unit test.
