Weston Pace commented on ARROW-14911:
-------------------------------------
I'm not sure the input data will be as important. If I am reading the test
correctly it initializes a random generator with a fixed seed. So even though
the test is testing random data it should be deterministic between runs. I
have verified that we are running this test on our CI servers (which includes
VS2017 although at a higher version than 19.12).
The test does do some parallel execution so there is a possibility it is a race
condition causing the flakiness.
I also built locally with VS2019 in both debug mode and release and tried
running this test both with and without CPU stress and have not been able to
reproduce it. I was doing this against the latest master and not the 6.0.1 tag
so that might be a factor. I will try and reproduce this some more tomorrow
with VS2017.
[[email protected]] How reliable is this failure? Does it fail every time or
intermittently? When it fails does it always display the exact same output?
(e.g. {{RIGHT SEMI IS_IS...}})
At the moment I'm not sure this qualifies as a blocker.

> arrow-compute-hash-join-node-test failed in my environment (windows, msvc
