ml.shifu.guagua.yarn.GuaguaYarnTask<MASTER_RESULT,WORKER_RESULT>

public class GuaguaYarnTask<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>
extends Object

GuaguaYarnTask is a entry point to run both master and workers.

partition should be passed as the last parameter in main. And it should be not be changed if we try another task.

Input split are now storing in guagua-conf.xml. We read data from there and check whether this task is master or worker.
