Subject [jira] [Commented] (HBASE-11354) HConnectionImplementation#DelayedClosing does not start
Date Mon, 23 Jun 2014 13:35:24 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14040742#comment-14040742
] 

Nicolas Liochon commented on HBASE-11354:
-----------------------------------------

Yes, if we:
 - close immediately the connection to ZK, it's likely a performance issue (w/ all the recent
changes may be it's not true anymore, but I doubt it)
 - don't close the connection to ZK, it's a scalability issue (typically with a load of mapReduce
clients).

> The method "createAndStart" in class DelayedClosing only creates a instance, but forgets
to start it. So thread delayedClosing is not running all the time.

>         Stoppable stoppable = new Stoppable() {
