Ismael Juma commented on KAFKA-2573:
------------------------------------
I think the test should fail fast indeed. The system tests are meant to test
the system working together and if one part is failing (for whatever reason),
we should know about it. This is one of the main benefits of system tests when
compared to the JUnit tests we have.
> Mirror maker system test hangs and eventually fails
