Lars Hofhansl commented on HBASE-4300:
--------------------------------------
For me TestReplicationSink and TestReplication timed out. When I revert this
change they finish again.
(I had some difficulty reverting this patch because the committed patch was
slightly different from the last file attached. For reasons like this I think
it would be generally useful if the patch that was actually applied - if
changed - is attached to the jira for future reference.)
