Subject [jira] [Commented] (HBASE-13694) CallQueueSize is incorrectly decremented until the response is sent
Date Fri, 15 May 2015 17:00:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14545785#comment-14545785
] 

stack commented on HBASE-13694:
-------------------------------

But if error, we need to decrement the callQueueSize and with your patch we will not [~esteban]

If we do this, we'll accumulate more responses in the server which we will be working on returning
to clients while letting more requests in the front door. You see CPU use go up [~esteban]

What is the 'other issue'?

> We should decrement the CallQueueSize as soon as we no longer need the call around, e.g.
after {{RpcServer.CurCall.set(null)}} otherwise we will be only pushing back other client
requests while we send the response back to the client that originated the call.
