[jira] [Created] (YARN-3161) Containers' information are lost in
some cases when RM restart
Jun Gong created YARN-3161:
------------------------------
Summary: Containers' information are lost in some cases when RM restart
Key: YARN-3161
URL: https://issues.apache.org/jira/browse/YARN-3161
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.6.0
Reporter: Jun Gong
When RM restart, containers' information will be lost for the following scenarios:
1. NM restarts before it sends containers' information to the new active RM.
2. NM stops and it could send containers' information to the new active RM.
Without those containers' information, corresponding AM will never get their status through RM, and AM could just wait them for ever.
