--------------------------------------------

             Summary: Make HBaseInterClusterReplicationEndpoint more extensible
                 Key: HBASE-23683
                 URL: https://issues.apache.org/jira/browse/HBASE-23683
             Project: HBase
          Issue Type: Improvement
            Reporter: Wellington Chevreuil
            Assignee: Wellington Chevreuil


*HBaseInterClusterReplicationEndpoint* currently creates the cluster connection and sink manager instances inside its _init_ method and assigns those to private class variables. Then any potential custom extension of *HBaseInterClusterReplicationEndpoint* that requires custom implementations of connection and/or sink manager would need to resort to _java reflection_ for effectively replace those instances, such as below:

{noformat}
...
    ClusterConnection conn = (ClusterConnection)ConnectionFactory.
      createConnection(context.getConfiguration(), User.create(replicationUgi));
    ReplicationSinkManager sinkManager = new ReplicationSinkManager(conn, ctx.getPeerId(),
      this, context.getConfiguration());
    try {
      Field field = this.getClass().getSuperclass().getDeclaredField("conn");
      field.setAccessible(true);
      field.set(this, conn);
      field = this.getClass().getSuperclass().getDeclaredField("replicationSinkMgr");
      field.setAccessible(true);
      field.set(this, sinkManager);
    } catch (Exception e) {
      throw new IOException(e);
    }
...
{noformat}
