Matt McCline commented on HIVE-8415:
------------------------------------

Thanks.  I removed HIVE-8391 changes and verified testCliDriver_parallel executes successfully
on my laptop.  New patch is #4.

> Current vectorization code treats integers as nanoseconds which doesn't match non-vectorized
Hive behavior that interprets integers and doubles as seconds since epoch.
> Currently, the patch includes Jason's changes from patch #2 in HIVE-8391.
