Daryn Sharp commented on YARN-1841:
-----------------------------------
I thought you were having issues talking to other services like a NN. As
noted, trying to communicate directly with the AMRM service is an invalid use
case. By design you cannot talk to this service w/o a token issued by the RM.
The RM must create the app id and app attempt for the AM prior to the AM
registering. I'd suggest leveraging the unmanaged AM.
