[jira] [Created] (TEZ-3306) Improve container priority assignments for vertices

Jason Lowe created TEZ-3306:
-------------------------------

             Summary: Improve container priority assignments for vertices
                 Key: TEZ-3306
                 URL: https://issues.apache.org/jira/browse/TEZ-3306
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Jason Lowe


After TEZ-3296 the priority space is sparsely used.  We should consider doing a breadth-first traversal of the DAG or reusing the client-side topological sorting to allow a more efficient use of the priority space.
