Subject [jira] [Commented] (HBASE-11964) Improve replication source thread handling
Date Fri, 12 Sep 2014 22:20:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11964?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14132208#comment-14132208
] 

Andrew Purtell commented on HBASE-11964:
----------------------------------------

I think what we want is for node failover work to be better distributed around the cluster,
rather than have one regionserver potentially win the lock when taking over for failed regionservers
much more often than other peers in the cluster, causing really uneven distribution of replication
work. 

The patch on this issue actually doesn't get to the core issue (yet) I think.

It might be useful to propose alternate changes here, or we can just resolve this as Later.
