[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.
