Matt McCline commented on HIVE-19275:
-------------------------------------
It would when HIVE-19269 goes in turning hive.vectorized.execution.enabled on.
However, this change should hopefully prevent any EXPLAIN plan output changes.
And, leave the Wrong Results / Execution Failures to investigated later.

> Quite a number of the bucket* tests had Wrong Results or Execution Failures.
> And others like semijoin, skewjoin, avro_decimal_native, mapjoin_addjar,
> mapjoin_decimal, nullgroup, decimal_join, mapjoin1.
> Some of the problems might be as simple as "-- SORT_QUERY_RESULTS" is missing.
> The bucket* problems looked more serious.
> This change sets "hive.vectorized.execution.enabled" to false at the top of
> those Q files.
