Ashu Pachauri commented on HBASE-14777:
---------------------------------------
It is a side effect of what I am doing. For the test, I am using the doPut call
that was already there is TestReplicationEndpoint, and using it quite a few
times in succession. From the logs, it seems that it is getting stuck and is
very slow because it goes the the generic HTable.put call.
Since, in my test, I have access to HRegion object, I am going to modify the
test to use directly do a region.put, which will be way faster.
