Matt McCline commented on HIVE-17895:
-------------------------------------
[~vihangk1] No, I have not checked on branch-2.
The trick I use in checking is to modify the "if (!vectorPath) {" in the
Vectorizer source to "if (!vectorPath || true) {" to temporarily disable
vectorization and then execute the Q file tests. I look for query result
differences in diffs. Occasionally, differences are due to a lack of "--
SORT_QUERY_RESULTS" in the Q file. But usually it is a different result but
not necessarily the fault of vectorization. Sometimes it is row-mode that is
in error.
