Rushabh S Shah commented on HDFS-13292:
---------------------------------------
Thanks [~RANith] for the patch.
There is whitespace warning. Please fix that.
The test case brings up an interesting point.
What if the user is trying to create an EZ with the same key with which it is
already created ?
Should it succeed and display some message like "An EZ is already created with
the same key."
Agree that it is tangential to this jira but just wanted to point it out.
If we decide to create another jira, I am fine with that.
+1 non-binding after fixing whitespace warning.
