[jira] Updated: (HBASE-2822) Enable Master-Master replication

["Jean-Daniel Cryans (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-2822?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jean-Daniel Cryans updated HBASE-2822:
--------------------------------------

    Fix Version/s: 0.21.0
      Description: 
There's nothing inherently wrong in the replication design that prevents master-master, but it was disabled in the code in order to reduce the scope of HBASE-2223. Specifically, this code from Replication just needs a simple 2 lines modification to always instantiate ReplicationSink if this.replication is true:

{code}
  public void startReplicationServices() throws IOException {
    if (this.replication) {
      if (this.replicationMaster) {
        this.replicationManager.init();
      } else {
        this.replicationSink =
            new ReplicationSink(this.conf, this.stopRequested);
      }
    }
  }
{code}

Enable and test.
