[jira] [Commented] (HBASE-7741) Don't use bulk assigner if assigning just several regions

["Jimmy Xiang (JIRA)" <ji...@apache.org>]

    [ 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).
