Joe McDonnell created IMPALA-6854:
-------------------------------------
Summary: TestExchangeDelays::test_exchange_small_delay()'s
implementation doesn't match description
Key: IMPALA-6854
URL: https://issues.apache.org/jira/browse/IMPALA-6854
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 3.1.0
Reporter: Joe McDonnell
test_exchange_small_delay() has this description:
{code:java}
def test_exchange_small_delay(self, vector):
"""Test delays in registering data stream receivers where the first one or two
batches will time out before the receiver registers, but subsequent batches
will
arrive after the receiver registers. Before IMPALA-2987, this scenario
resulted in
incorrect results.
"""
{code}
However, looking at the logs when the first sender times out, the query is
cancelled. In my manual tests, the query does not return a result. This test
case may be out of date. As it is, this overlaps with what
test_exchange_large_delay() is doing.
