Bikramjeet Vig commented on IMPALA-10596:
-----------------------------------------
So I tried to simulate this on my local by introducing a failed assert right
after we call self.wait_for_admitted_threads(metric_deltas['admitted']) and the
log line "Found all 6 admitted threads after 0.0 seconds" is printed. I noticed
that teardown is not called right away and instead all the running threads are
just waiting in the "while not self.shutdown" loop and when they error out of
that, the client gets closed and eventually teardown is called which then
errors out since the query_id was already closed when the client closed.
I'll push out a patch that removes the thread.query_handle if the client is
closed. That should fix this issue *and expose the real assert which was hit
that failed the test*. However, I am still not sure why the test just keeps
waiting for the other threads to finish before calling teardown.
