Subject [jira] [Resolved] (YARN-2055) Preemption: Jobs are failing due to AMs are getting launched and killed multiple times
Date Tue, 03 Nov 2015 17:21:27 GMT

     [ https://issues.apache.org/jira/browse/YARN-2055?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli resolved YARN-2055.
-------------------------------------------
    Resolution: Not A Problem

Between YARN-2074, MAPREDUCE-5956 and YARN-2022, this is not much of an issue anymore.

For the remaining toggle of AM containers between nearly full-queues, not much can really
be done.

I am closing this as not-a-problem anymore, please reopen as necessary.

> If Queue A does not have enough capacity to run AM, then AM will borrow capacity from
queue B to run AM in that case AM will be killed if queue B will reclaim its capacity and
again AM will be launched and killed again, in that case job will be failed.
