------------------------------------
Summary: Two RMNodes for the same NodeId are used in RM sometimes
after NM is reconnected.
Key: MAPREDUCE-6398
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6398
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.7.0
Reporter: zhihai xu
Assignee: zhihai xu
Two RMNodes for the same NodeId are used in RM sometimes after NM is
reconnected. Scheduler and RMContext use different RMNode reference for the
same NodeId sometimes after NM is reconnected, which is not correct. Scheduler
and RMContext should always use same RMNode reference for the same NodeId.
