Xiao Chen updated HADOOP-13539:
-------------------------------
Attachment: HADOOP-13539.01.patch
Patch 1 to express the idea.
Current behavior seems pretty odd: fail to remove master key = debug log; fail
to remove a token = RTE.
New behavior is to log a warn with some description indicating this maybe
harmless, with the actual exception.
[~andrew.wang], would you have time to review this? Thanks much!

> In {{ZKDelegationTokenSecretManager}}, the 2 methods
> {{removeStoredMasterKey}} and {{removeStoredToken}} are very much alike, yet
> handles exception differently. We should not throw RTE if a node cannot be
> removed - logging is enough.
