Examples of org.apache.tez.dag.api.Vertex.addOutput()

org.apache.tez.dag.api.Vertex.addOutput()

Specifies an Output for a Vertex. This is meant to be used when a Vertex writes Output directly to an external destination.

If an output of the vertex is meant to be consumed by another Vertex in the DAG - use the {@link DAG addEdge} method.If a vertex needs generate data to an external source as well as for another Vertex in the DAG, a combination of this API and the DAG.addEdge API can be used. @param outputName the name of the output. This will be used when accessing the output in the {@link LogicalIOProcessor} @param outputDescriptor @return

    // final vertices need to have at least one output
    if (!hasChildren) {
      v.addOutput("out_"+work.getName(),
          new OutputDescriptor(MROutput.class.getName())
          .setUserPayload(MRHelpers.createUserPayloadFromConf(conf)));
    }


    return v;
