Allan Yang commented on HBASE-18144:
------------------------------------
Hi, [~stack]， I uploaded a patch(HBASE-17924) with a UT to simulating
disordered batch and increment at the same time. Disordered batch put and
increment may be the root cause of your costumer's strange thread dump.
You can see, without of HBASE-17924, the UT will timeout and fail, but with
HBASE-17924, this UT can run normally. I haven't looked deep into it. But it
clearly showed there is a problem with lock efficiency.
> Forward-port the old exclusive row lock; there are scenarios where it
> performs better
