Subject [jira] Commented: (HBASE-1143) region count erratic in master UI (kill server hosting root or meta and see how count goes awry).... make sure you have a bunch of reions in there

    [ https://issues.apache.org/jira/browse/HBASE-1143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12715658#action_12715658

Jean-Daniel Cryans commented on HBASE-1143:
-------------------------------------------

I tried this. What I see after killing the .META. holding RS is that we lose a bunch of edits
so we only see an old version of the .META. table coming back. That version, if you killed
your RS not long after the cluster startup, is a snapshot of .META. on the last shutdown.
What I saw is a bunch of "Current assignment of ...", just like a fresh start!

Now I restarted HBase and tested again but I first flushed .META. and, guess what, everything
was fine. IMO we should flush/compact .META. like crazy until we are able to not lose edits.
That region is always small so it seconds < 1 sec to do.
