Subject [jira] [Commented] (HBASE-14239) Branch-1.2 AM can get stuck when meta moves
Date Thu, 20 Aug 2015 18:35:46 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14239?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14705525#comment-14705525

Enis Soztutar commented on HBASE-14239:

bq. I'm trying to refresh my brain as to whether HBASE-13480 is just a wholly better goal
Good catch. Agreed that this is probably due to HBASE-13480 if it it meta colocation with
bq.  I hold no stake in a revert or not, but I'd be afraid the deadlock is still there post-revert
if reportRegionStateTransition() uses a normal priority handler, and that handler does a meta
request which uses a priority handler, it may work. But it seems fragile. HBASE-13480 seems
to be the proper fix.
