Subject [jira] Updated: (HBASE-3332) Regions stuck in transition after RS failure
Date Fri, 10 Dec 2010 20:29:01 GMT

     [ https://issues.apache.org/jira/browse/HBASE-3332?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jonathan Gray updated HBASE-3332:

    Attachment: HBASE-3332-v1.patch

Previously ServerShutdownHandler would not handle any regions on the dead server if they were
already in transition.  However, in the TimeoutMonitor, we will never force a region off of
a server when it's PENDING_CLOSE or CLOSING because the expectation was we would handle it
in server expiration.  But again, over there, we did nothing to all RIT.

Change makes it so we will force reassignment of RIT if PENDING_CLOSE or CLOSING.

Patch is not done yet, I need to make sure master won't screw something up and I want to add
a test.

> Testing 0.90rc2 I ran into this issue. The test scenario was to kill -9 the server hosting
ROOT and META, and before it had been detected, run "balancer" from the shell. After logs
were split and regions were reassigned, I ended up with some regions stuck in transition.
