Attila Doroszlai commented on HDDS-3104:
----------------------------------------

bq. ExitUtil is called while stopping the DN when the test is done.

The test might have passed otherwise, but from Surefire's point of view it does 
not complete normally if it exits explicitly.  We should avoid it.

Clarification: this problem is not specific to 
TestContainerStateMachineFailureOnRead, I've [seen it 
happen|https://github.com/apache/hadoop-ozone/pull/556#issuecomment-591963029] 
for other integration test, too.
