---------------------------------------
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;
}
> Job Priority is not changing
