Eric Hanson updated HIVE-5756:
------------------------------
Attachment: HIVE-5756.6.patch.txt
I combined the patch HIVE-5756.5.patch with the one for string IF (HIVE-5807)
because I think I fixed some of the issues Jitendra pointed out with the patch
for strings. I now plan to do the work for all the types, including strings,
under this JIRA.
> Implement vectorization support for IF conditional expression for long,
> double, timestamp and boolean inputs

> Implement full, end-to-end support for IF in vectorized mode, including new
> VectorExpression class(es), VectorizationContext translation to a
> VectorExpression, and unit tests for these, as well as end-to-end ad hoc
> testing. An end-to-end .q test is recommended but optional.
> This is high priority because IF is the most popular conditional expression.
