Chia-Ping Tsai commented on HBASE-19715:
----------------------------------------
bq. Would making our batches smaller help?
The story is about the cost of handling the exception is directly proportional
to the batch size. Ya, we can add some suggestion to user about the side effect
of large batch. But I think what [~appy] are trying is to reduce the cost -
make it not proportional to the batch size at least.

> Correlating across more runs, whenever the tests passes, it does so within
> 10-30sec of 3min deadline for medium tests.
> So i think we can make it pass by just increasing the timeout.
> But I'm a bit skeptical after seeing all those long GC pauses (10sec +) in
> the log. Test code doesn't seem to be doing anything that intensive. Are we
> mismanaging the memory somewhere?
