             Summary: Containers not getting released if app is killed in the middle of execution
                 Key: TEZ-2759
                 URL: https://issues.apache.org/jira/browse/TEZ-2759
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Rajesh Balamohan


Steps to reproduce (taking example of hive as it is easier to reproduce):
1. Launch tez session and run a hive query.
2. "ctrl+c" in the middle of query execution
3. This kills the query. However, the appmaster does not release all the containers it had. It randomly retains some containers and they are released only after AM timeouts (i.e after tez.session.am.dag.submit.timeout.secs)

Impact is that, there can be unused containers and this can cause potential cluster underutilization.

Will attach the logs soon.
