[jira] [Created] (MAPREDUCE-2749) [MR-279] NM registers with RM even before it starts various servers

[MR-279] NM registers with RM even before it starts various servers
-------------------------------------------------------------------

                 Key: MAPREDUCE-2749
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2749
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.0
            Reporter: Vinod Kumar Vavilapalli
             Fix For: 0.23.0


In case NM eventually fails to start the ContainerManager server because of say a port clash, RM will have to wait for expiry to detect the NM crash.

It is desirable to make NM register with RM only after it can start all of its components successfully.
