Subject [jira] [Commented] (HBASE-2195) Support cyclic replication
Date Thu, 08 Sep 2011 04:21:11 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13099757#comment-13099757

stack commented on HBASE-2195:
------------------------------

You think we should expose this version Ted?  I'd think it an internal implementation detail.
  Hopefully, the case should be that the clients never have to worry what version their HLogKey
is.  It always just works whatever data format is thrown at it because internally it'll do
the right thing instantiating an HLogKey though given version 0 or version 1 data.  It seems
like HLogKey does what VersionedWritable adds (but for the getVersion method)

> We need to support cyclic replication by using the cluster id of each HlogKey and stop
replicating when it goes back to the original cluster.
