Examples of cascading.flow.Flow.start()

cascading.flow.Flow.start()
Method start begins the execution of this Flow instance. It will return immediately. Use the method {@link #complete()}to block until this Flow completes.


    // connect the assembly to the SOURCE and SINK taps
    Flow parsedLogFlow = new FlowConnector(properties).connect(logTap, remoteLogTap, pipeline);


    // start execution of the flow (either locally or on the cluster
    parsedLogFlow.start();


    // block until the flow completes
    parsedLogFlow.complete();
  }
}

    // optionally print out the parsedLogFlow to a DOT file for import into a graphics package
    // parsedLogFlow.writeDOT( "logparser.dot" );


    // start execution of the flow (either locally or on the cluster
    parsedLogFlow.start();


    // block until the flow completes
    parsedLogFlow.complete();
    }
