Subject [jira] [Commented] (HBASE-12880) RegionState in state SPLIT doesn't removed from region states
Date Wed, 21 Jan 2015 10:48:36 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14285477#comment-14285477

Andrey Stepachev commented on HBASE-12880:

[~jxiang] Not too many. Even here shouldn't be more then twice of latter splits. Seems housekeeping
will make RegionStates more complicated then necessary. I'd prefer to close this as Wan't

> During my work on patch HBASE-7332 I stumbled on strange behaviour in RegionStates. Split
region doesn't removed from regionStates in regionOffline() method and RegionState for this
region sits in regionStates map indefinitely long (until RS rebooted).
> (that is clearly seen in HBASE-7332 by simple creating table and splitting it from command
> Is that was intended to be so and some chore eventually will remove it from regionStates
(didn't find with fast code scanning) or here can be resource leak?
