Duo Zhang commented on HBASE-15389:
-----------------------------------

The testcase fail on branch-1 is unrelated.

I have checked the code, the failed assertion is 
{code}
assertTrue(throughput > throughputLimit * 0.8);
{code}
which means the throughput is too low.

I think a very slow machine can cause this problem. And for the testcase 
itself, the time cost of creating table is also included as the flush time 
which makes it easier to calculate a smaller throughput. [~carp84] I think we 
should modify the time keeping part of this testcase? Thanks.
