[jira] [Commented] (HBASE-11991) Region states may be out of sync

    [ https://issues.apache.org/jira/browse/HBASE-11991?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14136123#comment-14136123 ] 

stack commented on HBASE-11991:
-------------------------------

nit: Declare and assign in the one step instead of in two as you have it here:

+    oldAssignments = new HashMap<String, ServerName>();

Can you say more about what this old state is helping with?  I think I get it and the patch looks good but a sentence or two would make me more confident I understand what is going on when I +1

> Region states could be out of sync under a rare scenario. The regions hosted by a server could be wrong.
