Omkar Vinit Joshi commented on YARN-613:
----------------------------------------
Small update to RM issuing the AMNMToken to AM :-
* RM will clear its cache after master key is rolled over. Thereby if AM is
allocated a new container after key rollover then it will be issued new
AMNMToken
* NM similarly will remember previous key only for twice (to be safer) the key
activation period of RM.
> Create NM proxy per NM instead of per container
