Subject [jira] Updated: (HBASE-2414) Enhance test suite to be able to specify distributed scenarios
Date Fri, 23 Apr 2010 19:18:50 GMT

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

stack updated HBASE-2414:
-------------------------

    Attachment: testmaster-v5.patch

This version better integrates the use of nonetwork implementations of pertinent interfaces.
 Not done yet.  Need to work it into HBaseTestingUtility better and still need to prove that
testing cluster transistion with this stuff is viable (it still looks so, just need to do
the proof still).   If want to take a look now, start with TestClusterTransistions.

> 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.
