> *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}
