[jira] [Created] (YARN-5333) apps are rejected when RM HA
Jun Gong created YARN-5333:
------------------------------
Summary: apps are rejected when RM HA
Key: YARN-5333
URL: https://issues.apache.org/jira/browse/YARN-5333
Project: Hadoop YARN
Issue Type: Bug
Reporter: Jun Gong
Assignee: Jun Gong
Enable RM HA and use FairScheduler.
Reproduce steps:
1. Start two RMs.
2. After RMs are running, change both RM's file {{etc/hadoop/fair-scheduler.xml}}, then add some queues.
3. Submit some apps to the new added queues.
4. Stop the active RM, then the standby RM will transit to active and recover apps.
However the new active RM will reject recovered apps because it might have not loaded the new {{fair-scheduler.xml}}. We need call {{initScheduler}} before start active services or bring {{refreshAll()}} in front of {{rm.transitionToActive()}}. *It seems it is aslo important for other scheduler*.
