Subject [jira] [Commented] (HBASE-11756) Some assignment notifications are not triggered
Date Fri, 15 Aug 2014 17:49:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14098814#comment-14098814

Jimmy Xiang commented on HBASE-11756:

Not that. It's about the notification for those AssignmentListeners. For, AM has its own regionOffline
method, in which it calls sendRegionClosedNotification(). Sometimes, RegionStates#regionOffline
is called directly so the notification call is not invoked.

> In AssignmentManager, notifications are triggered when regions are opened/closed. However,
notifications are not always triggered. For example, when a server is dead, regions are closed
implicitly, and no notifications are triggered.
> Is it a better place to trigger such events in RegionStates?
