[jira] Commented: (HBASE-1157) If we do not take start code as a part of region server recovery, we could inadvertantly try to reassign regions assigned to a restarted server with a different start code

    [ https://issues.apache.org/jira/browse/HBASE-1157?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12681994#action_12681994 ] 

stack commented on HBASE-1157:
------------------------------

Just wondering, did you talk w/ the ZKBoys about whether or not ZK already has a mechanism differentiating different regionservers in ZK?

Above you say "While we might use a different mechanism after ZK integration, the ZK integration still needs to account for what instance of the regionserver it is dealing with."  How does this patch help the ZK integration effort? 

(I ask because you just made a fairly large commit without general notes on what is in the commit).
