------------------------------
Thanks [~xuefuz] and [~brocknoland]. I'll try {{-- SORT_QUERY_RESULTS}} instead.
But it seems adding that to the qfiles caused these tests fail for MR and Tez
since the output files are different now. Do you think I should update the
output for MR and Tez as well?

> HiveKey should be used as the key type because it holds the hash code for
> partitioning. While BytesWritable serves partitioning well for simple cases,
> we have to use {{HiveKey.hashCode}} for more complicated ones, e.g. join,
> bucketed table, etc.
