Description
A Jenkins run hung while running test_mini_stress.py::test_mini_stress.
Observations at the time of the hang:
- There are a total of 64 FE connections in use.
- There are 15 active queries that returned results. Their latest timeline event is "UnregisterQuery" from which there is no more progress.
Attached:
- Backtraces of all threads of the impalad processes at the time of the hang
- Raw JSON of the impalad metrics at the time of the hang
I have not yet tried to reproduce locally. This is my first run of this test in this configuration, so I assume it should be easy to reproduce.
