-------------------------------------
Found with a large query. Need to come up with a small repro that can be made
into a Q file.
> Vectorization: Vectorized PTF operator should not set the initial type infos

> Key: HIVE-18531
> URL: https://issues.apache.org/jira/browse/HIVE-18531
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 3.0.0
> Reporter: Matt McCline
> Priority: Critical
>
> The Vectorized PTF operator is mistakenly setting the initial type infos for
> its output VectorizationContext. It should not. It is only creating a
> projection of the initial columns from ReduceSink (i.e. keys, values) plus
> scratch columns for output columns.
