             Summary: Support for Tez Job Submission Priority
                 Key: TEZ-2627
                 URL: https://issues.apache.org/jira/browse/TEZ-2627
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Saikat


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.
