I got a +1 over on HBASE-10449 from the man himself, [~nkeywal]
We need to test but for now will live with less threads till proved we need
more.
> Set down the client executor core thread count from 256 to number of

> HBASE-10449 upped our core count from 0 to 256 (max is 256). Looking in a
> recent test run core dump, I see up to 256 threads per client and all are
> idle. At a minimum it makes it hard reading test thread dumps. Trying to
> learn more about why we went a core of 256 over in HBASE-10449. Meantime will
> try setting down configs for test.
