Vinod Kumar Vavilapalli updated MAPREDUCE-2749:
-----------------------------------------------
Assignee: Thomas Graves
One complication is that NM gets the shared secret from RM only after
registration and the ContainerManager server needs these to be set for
authenticating user requests. For addressing this, we can start the server,
inform the RM, get the tokens and *set* them on the server.
[~tgraves] indicated that he can look into this, so assigning it to him.
> [MR-279] NM registers with RM even before it starts various servers
