Hey all! We've tried to upgrade to Tez to 0.9.2 in Hive - but we have hit some non-deterministic hang issue. So we've rolled back to 0.9.1 for now (see:[1]).
I've collected some jstacks from the running tests which have were stuck for more than 20 hours - there are 2-3 tests which were able to trigger it: https://termbin.com/z1eoc https://termbin.com/2m0j https://termbin.com/027t https://termbin.com/1dbe There is a job which could be used to check/reproduce the issue: http://130.211.9.232/job/hive-flaky-check/51/ Let me know if I could help!
