-
I did suspect a bug, too, and did include the seed :) – Just did not know that
we also need the strategy? Given that we don't have a lot of strategies, seems
we could rerun each strategy with the given seed and one should just fail?

By the way – if this test is failing, it's highly likely that this is a real
bug. This test was designed to be completely deterministic (hence the seed) and
doesn't set up any actual clients or clusters or anything that might make it
flaky. [~mjsax] if you see this again can you report the failure here
(including both the seed and rackAwareStrategy parameter)?

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
