[jira] [Created] (PIG-3602) Tear down TezSessions when Pig exits

Cheolsoo Park created PIG-3602:
----------------------------------

             Summary: Tear down TezSessions when Pig exits
                 Key: PIG-3602
                 URL: https://issues.apache.org/jira/browse/PIG-3602
             Project: Pig
          Issue Type: Sub-task
          Components: tez
    Affects Versions: tez-branch
            Reporter: Cheolsoo Park
             Fix For: tez-branch


Currently, Pig reuses AMs via TezSession, but they are not shut down when Pig exits. There are two problems that I noticed with this-
# Tez jobs are not marked as finished until TezSessions are expired after timeout. Since they occupy task slots, it blocks submitting jobs.
# ant clean test-tez leaves orphan processes (DAGAppMaster).

Ideally, TezSession should be kept alive while Pig runs but tore down when Pig exits.
