Subject [jira] [Commented] (HBASE-11096) stop method of Master and RegionServer coprocessor is not invoked
Date Wed, 30 Apr 2014 18:02:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11096?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13985846#comment-13985846

Andrew Purtell commented on HBASE-11096:
----------------------------------------

bq. Failed tests: testNativeSizes

Non Oracle JVM? Anyway this will be unrelated to this patch. 

Please log at debug level and add a check for if debug logging is enabled (skips string formatting
costs if not), e.g.
{code}
if (LOG.isDebugEnabled()) {
    LOG.debug(...)
}
{code}

If possible please add or modify a unit test to confirm the stop method is invoked.

> the stop method of coprocessor specified by "hbase.coprocessor.master.classes" and  "hbase.coprocessor.regionserver.classes"
 is not invoked.
> If coprocessor allocates OS resources, it could cause master/regionserver resource leak
or hang during exit.
