------------------------------------
Summary: check_num_executing fails test_query_expiration
Key: IMPALA-14188
URL: https://issues.apache.org/jira/browse/IMPALA-14188
Project: IMPALA
Issue Type: Bug
Reporter: Fang-Yu Rao
Assignee: Riza Suminto
We found that {{test_query_expiration()}} in
https://github.com/apache/impala/blame/master/tests/custom_cluster/test_query_expiration.py
could fail in {{_check_num_executing()}} because the number of in-flight
queries in the waiting state was 1, but we expected this number to be 0 based
on the following stacktrace.
{code}
custom_cluster/test_query_expiration.py:124: in test_query_expiration
self._check_num_executing(impalad, 2)
custom_cluster/test_query_expiration.py:52: in _check_num_executing
assert waiting == expect_waiting, (
E AssertionError: 1 out of 3 queries waiting (expected 0).
query_id=[u'3343c5b0633c8f84:e3bc421f00000000']
E assert 1 == 0
{code}
According to the log lines above, it looks like
- 3 queries were in-flight,
- 2 queries were in the executing state, and
- 1 query was in waiting state
Not very sure if I missed something, but it seems there was one more in-flight
query than expected?
