Jason Lowe commented on TEZ-3695:
---------------------------------
{{testAwaitTermination}} looks like it could have similar racing issues since
it has the same assumptions when it calls {{notify}}, but that test has a 100
msec timer hack that would make it less likely in practice. Again a
{{CountdownLatch}} would make this faster and more deterministic.
> TestTezSharedExecutor fails sporadically
