Subject [jira] [Commented] (HBASE-8106) Test to check replication log znodes move is done correctly
Date Fri, 15 Mar 2013 00:00:13 GMT

Himanshu Vashishtha commented on HBASE-8106:
--------------------------------------------

Thanks for the review Lars.
I tried to create a more "realistic" scenario where three regionservers are trying to move
the znodes. 
If we keep the hostname same, then also the test will pass. But, the exception will be different:
it will be a "NodeExists" exception because all the nodefailoverworkers will try to create
same set of znodes in the target. Rather, if we keep them separate, then we get NoNodeException,
indicating that the log znode which NodeFailoverworker is trying to copy/move no longer exists
at the source(as it is already moved by some other regionserver). Please let me know if you
still need the same hosts.
