Description

When a Tez Job is submitted via TezClient, an ApplicationSubmissionContext is created before submitting the job. ApplicationSubmissionContext has a priority field which can be used to provide a priority for the job.

There is an ongoing effort in the Yarn Community to enable application priorities(https://issues.apache.org/jira/browse/YARN-1963).

https://issues.apache.org/jira/browse/YARN-2003 implements the necessary changes in RM and Capacity Scheduler.
