IMPALA-5427: Fix order of status handling in ClientRequestState
There was a race in ClientRequestState::UpdateQueryStatus() leading to
the rare situation that a query would abort with an error, but the error
message would be empty.
The fix is to update the query_status_ before setting it to preserve the
error message.
To test this I ran test_corrupt_files in a loop for 2 days. 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
