Description

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.
