Subject Re: [jira] [Commented] (HBASE-8156) Support for Namenode HA for non-idempotent operations
Date Mon, 25 Mar 2013 18:38:42 GMT
And
coprocessor.TestMasterObserver.testRegionTransitionOperations(TestMasterObserver.java
passes me at local. I am wondering if something is wrong this patch, or is
it some environmental issue which is causing this. Going by the patch and
pattern of the failures, I don't see any relation b/w them. Please let me
know if you think different.
