László Bodor commented on TEZ-4119:
-----------------------------------
yes [~ahussein], I've seen it in recent precommit tests
my experience was that if I run only TestSpeculation, it passes quickly, but if
I run mvn clean test for whole tez-dag submodule, it will more likely fail,
hope this helps to reproduce
