Subject [jira] [Commented] (HBASE-11756) Some assignment notifications are not triggered
Date Fri, 15 Aug 2014 17:25:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14098782#comment-14098782
] 

Mikhail Antonov commented on HBASE-11756:
-----------------------------------------

"notifications not being triggered" - you mean, region is left in 'opened" state until next
RS 's ephemeral znodes expires, and when master notices that, is marks all regions hosted
by that RS as "closed"?

> Some assignment notifications are not triggered

> 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?
