Subject [jira] [Commented] (YARN-5315) Standby RM keep sending start am container request to NM
Date Wed, 06 Jul 2016 18:57:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-5315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15364888#comment-15364888

Vinod Kumar Vavilapalli commented on YARN-5315:

shutdownNow() still does not wait for actively executing tasks to terminate. You should make
an explicit awaitTermination() call to do that.

We should also call "super.serviceStop()" to complete the life-cycle, can you make that change
