Subject [jira] [Commented] (HADOOP-10278) Refactor to make CallQueue pluggable
Date Mon, 03 Feb 2014 23:21:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10278?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13890095#comment-13890095

Daryn Sharp commented on HADOOP-10278:

Given my current focus on performance, it saddens me that the get+poll would be noticeable.
 Did you try tinkering with the poll time?  Perhaps some number of seconds is a reasonable
time for handlers to switch over to a new queue since I would expect that queue swapping would
be an infrequent event.

Please go ahead and post the patch.  It's really the combination of performance and simplicity/maintainability
that should be the determining factors.
