xieguiming commented on MAPREDUCE-4124:
---------------------------------------

1, When jobclient create the ApplicationSubmissionContext, set the priority to the ApplicationSubmissionContext.
    {color:red} 
    Priority pri = Records.newRecord(Priority.class); // Job Priority.
    pri.setPriority(jobConf.getInt(JobContext.PRIORITY,
        YarnConfiguration.DEFAULT_PRIORITY));
    appContext.setPriority(pri);
   {color} 
    appContext.setAMContainerSpec(amContainer);         // AM Container

2, Add one interface function in the ClientRMProtocol. and implement the function:
     public void setJobPriority(JobID arg0, String arg1) throws IOException,
      InterruptedException {
        {color:red} 
       // call the ClientRMProtocol.setApplicationPriority()
       {color} 
       return;
     }
