Subject [jira] [Commented] (HBASE-7741) Don't use bulk assigner if assigning just several regions
Date Sun, 03 Feb 2013 16:54:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7741?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13569812#comment-13569812

Jimmy Xiang commented on HBASE-7741:
------------------------------------

Thanks, Ram.  I was wondering should we handle not just one region.  In small cluster, especially
the mini cluster for testing, using bulk assignment has some overhead in creating threads.
 It is not a big deal.  But it could time out some unit test cases, for example, HBASE-7502
(I think it is related to region assignment latency. In mini cluster, all servers are in the
same JVM, the thread scheduling may slow down something).
