     [ https://issues.apache.org/jira/browse/HBASE-2414?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-2414.
--------------------------

    Hadoop Flags: [Reviewed]
      Resolution: Fixed

Committed to branch and trunk.  Thanks for review Karthik.  I committed with your suggested changes.  I'm resolving this issue though I'm sure there is probably a better way of testing cluster transitions.  This should do for now.  We can open a new JIRA for NG or improvements.

> We keep finding good cases that are reasonably hard to test, yet the test suite does not encode these. 
> For example: 
> HBASE-2413 Master does not respect generation stamps, may result in meta getting permanently offlined
> HBASE-2312 Possible data loss when RS goes into GC pause while rolling HLog
> I am sure there are many more such "scenarios" we should put into the unit tests.
