Vinod Kumar Vavilapalli commented on YARN-2208:
-----------------------------------------------
bq. Should we cache the am token password instead of re-computing password each
time rpc is invoked?
This is a micro-optimization. Let's get rid of caching the passwords - that way
we are consistent with other token-handling in the system.
> AMRMTokenManager need to have a way to roll over AMRMToken
