Hello Zoltan, Thank you for this.
So, I ran few tests under itests to replicate the issue. There are 10 files inside itests which use Tez in one form or the other. I ran tests for all. All of them finished with maximum one running duration for 8 mins. Below are the timings for all |Testname|Duration| |TestMmCompactorOnTez| 3.41 min| |TestAcidOnTez|| |TestCrudCompactorOnTez| 4.00 min| |TestBeeLineWithArgs| 2.59 min| |TestCopyUtils| 49 s| |TestTriggersTezSessionPoolManager| 22 s| |TestTriggersWorkloadManager| 21 s| |TestTriggersNoTezSessionPool| 1.50 min| |TestTezPerfConstraintsCliDriver| 8 min | I am not sure what is causing the issue seen on the build server.
