[jira] [Created] (TEZ-3985) Correctness: Throw a clear exception for DMEs sent during cleanup

Gopal V created TEZ-3985:
----------------------------

             Summary: Correctness: Throw a clear exception for DMEs sent during cleanup
                 Key: TEZ-3985
                 URL: https://issues.apache.org/jira/browse/TEZ-3985
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Gopal V


If a DME is sent during cleanup, that implies that the .close() of the LogicalIOProcessorRuntimeTask did not succeed and therefore these events are an error condition.

These events should not be sent and more importantly should be received by the AM.

Throw a clear exception, in case of this & allow the developers to locate the extraneous event from the backtrace.
