Subject [jira] [Commented] (YARN-8606) Opportunistic scheduling doesnt work after failover
Date Tue, 31 Jul 2018 17:41:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-8606?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16564054#comment-16564054

Suma Shivaprasad commented on YARN-8606:

Thanks for the patch [~bibinchundatt]. createApplicationMasterService is already registering
an EventDispatcher for OpportunisticContainerAllocatorAMService when opportunistic scheduling
is enabled in RMActiveServices composite service. Can you pls explain what is the issue and
what this patch intends to fix?
