Subject [jira] [Updated] (YARN-5333) Some recovered apps are put into default queue when RM HA
Date Tue, 12 Jul 2016 16:02:20 GMT

     [ https://issues.apache.org/jira/browse/YARN-5333?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jun Gong updated YARN-5333:
---------------------------
    Description: 
Enable RM HA and use FairScheduler, {{yarn.scheduler.fair.allow-undeclared-pools}} is set
to false, {{yarn.scheduler.fair.user-as-default-queue}} is set to false.

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 put recovered apps into default queue 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
also important for other scheduler*.
