to look at the new patch set (#13).
Change subject: IMPALA-5427: Fix race between CRS::UpdateQueryStatus() and
beeswax RPCs

IMPALA-5427: Fix race between CRS::UpdateQueryStatus() and beeswax RPCs
There was a race between ClientRequestState::UpdateQueryStatus() and the
beeswax get_state()/get_log() RPCs leading to the rare situation that a
query would abort with an error, but the error message would be empty.
The fix is to take the ClientRequestState lock in the beeswax RPCs
before obtaining the status.
To test this I ran test_corrupt_files in a loop for a day. Without this
fix, it would usually fail within a few hours.
I changed the test to allow running it in parallel like so:
@pytest.mark.parametrize('multiplier', xrange(32))
def test_corrupt_files(self, vector, multiplier):
Then I ran it in a loop like so:
i=0; while [ $? -eq 0 ]; do ((++i)); echo "Run: $i"; impala-py.test \
tests/query_test/test_scanners.py::TestParquet::test_corrupt_files \
--exploration_strategy=exhaustive -n8; done
