Subject [jira] [Commented] (HBASE-12936) Quota support for namespace should take region merge into account
Date Wed, 28 Jan 2015 18:25:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14295563#comment-14295563

Andrew Purtell commented on HBASE-12936:
----------------------------------------

Well, the question is should the listener be notified before or after the AM changes its state.
What do you think is better?

> HBASE-8410 added basic quota support for namespaces.
> However, region merge operation was not taken into account. This means, once region count
limit is reached, user table cannot be split even after some regions are successfully merged.
> This issue fixes the bug by adding hook in RegionStateListener for region merged event.
