Date Mon, 17 Jan 2011 19:19:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12982809#action_12982809

stack commented on HBASE-3447:
------------------------------

Any more in the log from around here?

{code}
logs/HM-haus01.sf.cloudera.com.log:2011-01-16 18:03:26,164 DEBUG oahh.M.handler.ServerShutdownHandler:
Offlined and split region usertable,user136857679,1295149082811.9f2822a04028c86813fe71264da5c167.;
checking daughter presence
{code}

The RS seems to report fine that the parent if split/offlined:

{code}
logs/RS-haus04.sf.cloudera.com.log:2011-01-16 17:51:44,112 INFO oahh.RS.CompactSplitThread:
Region split, META updated, and report to master. Parent=usertable,user136857679,1295149082811.9f2822a04028c86813fe71264da5c167.,
new regions: usertable,user136857679,1295229096477.ea26a71066b5617d9d8c9a4394209895., usertable,user1372334755,1295229096477.9c05ac3446fd2ff2d0cc0ac78f063867..
Split took 7sec
{code}

... and the master on shutdown processing seems to recognize it as an offlined parent.

Is this the one you figured when we talked on IRC?
