Also down the keepalive from a minute to ten seconds. Also set it so in test runs the keepalive is three seconds and the core thread count is 4 only in an effort at keeping down our resource usage/thread count when tests are running. > Set down the client executor core thread count from 256 to number of processors > ------------------------------------------------------------------------------- > > Key: HBASE-14433 > URL: https://issues.apache.org/jira/browse/HBASE-14433 > Project: HBase > Issue Type: Sub-task > Components: test > Reporter: stack > Assignee: stack > Attachments: 14433 (1).txt, 14433.txt, 14433v2.txt > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
