Subject [jira] [Commented] (HBASE-13773) Replication should not use ZooKeeper at all for coordination
Date Sun, 25 Oct 2015 03:28:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13773?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14972979#comment-14972979
] 

Heng Chen commented on HBASE-13773:
-----------------------------------

What about {{ReplicationQueues}}?  

If zk removed, how the slaves get notified by master if there are some new wals to replicate?
 Polling by slave?
