Subject [jira] [Commented] (YARN-9005) FairScheduler maybe preempt the AM container
Date Sat, 10 Nov 2018 06:47:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-9005?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16682243#comment-16682243
] 

Yufei Gu commented on YARN-9005:
--------------------------------

It is by design that AM containers can be preempted. YARN-5830 did the improvement to reduce
the chance of preempting AM containers. FS still preempts AM containers if that is the only
option.

> In the worst case, FS preempt the AM container. Due to FSPreemptionThread#identifyContainersToPreempt
return value contains AM container.
