Subject [jira] [Commented] (HBASE-2730) Expose RS work queue contents on web UI
Date Mon, 09 Jul 2012 07:30:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13409241#comment-13409241
] 

Jie Huang commented on HBASE-2730:
----------------------------------

Just ignore the previous patch and comments on RS in transition. Since I found that we needn't
to dump those regions under opening or closing in the queue-dump. That work is already done
in the Master-Status. I wonder if it is OK for the queque-dump patch.

> Would be nice to be able to see the contents of the various work queues - eg to know
what regions are pending compaction/split/flush/etc. This is handy for debugging why a region
might be blocked, etc.
