Sergey Shelukhin commented on HIVE-11431:
-----------------------------------------
This (or a very similar top of callstack) also happens for simpler queries -
e.g. select * from foo where string_id in (1234, 134535, 4545) (in has
integers, the in column is a string)
> Vectorization: select * Left Semi Join projections NPE
> ------------------------------------------------------

> Key: HIVE-11431
> URL: https://issues.apache.org/jira/browse/HIVE-11431
> Project: Hive
> Issue Type: Bug
> Components: Vectorization
> Affects Versions: 1.3.0, 1.2.1
> Reporter: Gopal V
> Assignee: Matt McCline

>
> The "select *" is meant to only apply to the left most table, not the right
> most - the unprojected "d" from tmp1 triggers this NPE.
> {code}
> select * from tmp2 left semi join tmp1 where c1 = id and c0 = q;
> {code}
> {code}
