A. Sophie Blee-Goldman commented on KAFKA-16586:
------------------------------------------------
Note: when reporting an instance of failure for this test, please include both
the seed (contained in the stack trace, eg
"runRandomizedScenario(-3595932977400264775)") and the full test name including
parameters (not present in the original ticket description, eg
"rackAwareStrategy=balance_subtopology")
We need the test name to figure out which variant of the assignor was running.
This will help narrow down the issue to a specific rackAwareStrategy, as well
as enable reproduction of the failed test
