----------------------------
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.
