> 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 This test case may be out of date.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.
