Subject [jira] [Updated] (HBASE-14433) Set down the client executor core thread count from 256 in tests
Date Wed, 16 Sep 2015 15:56:46 GMT

     [ https://issues.apache.org/jira/browse/HBASE-14433?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-14433:
--------------------------
    Release Note: Tests run with client executors that have core thread count of 4 and a keepalive
of 3 seconds. They used to default to 256 core threads and 60 seconds  for keepalive.  (was:
Change the client executor core thread count to be number of processors instead of 256: i.e.
the equivalent of the maximum threads allowed on client. The config to set it back to 256
or any other value is "hbase.hconnection.threads.core".

Also set it so core is set to default 4 threads in client core in tests (and keepalive is
downed from a minute to 3 seconds).)
         Summary: Set down the client executor core thread count from 256 in tests  (was:
Set down the client executor core thread count from 256 to number of processors)

> 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.
