Lars Volker commented on IMPALA-6591:
-------------------------------------
I've seen this again. Here's the code loop with the failed assertion:
{code}
# In practice, sending SIGINT to the shell process doesn't always seem to get
caught
# (and a search shows up some bugs in Python where SIGINT might be ignored). So
retry
# for 30s until one signal takes.
while impalad.get_num_in_flight_queries() == 1:
time.sleep(1)
LOG.info("Sending signal...")
os.kill(p.pid(), signal.SIGINT)
num_tries += 1
assert num_tries < 30, "SIGINT was not caught by shell within 30s"
{code}
{{p}} is an {{ImpalaShell}} object. There seems to be a possibility that the
shell process has been terminated but the query is still registered. I think we
should at least improve the code to log if the shell process is still alive to
tell the two cases apart and better understand where to look next.
