Omkar Vinit Joshi commented on YARN-692:
----------------------------------------
As a part of this patch only enabling following features.
* During start RM generates NMTokenMasterKey
* For Every NodeManager registration master key is shared along with
containerTokenMasterKey
* If there is a rollover then in the hearbeat master key will be shared.
RM at present doesn't send NMToken at container allocation (will be there in
YARN-693).
AM at present doesn't store NMToken ...(will be there in YARN-693)
AM at present doesn't send these tokens to NM for all AM-NM communication (will
be there in YARN-694).
NM at present doesn't verify the NMToken (will be there in YARN-694).
Added test cases to verify RMNMSecretKeys - at rm start and at roll over.
> Creating AMNMToken master key on RM and sharing it with NM as a part of RM-NM
> heartbeat.
