> NPE in Hive windowing functions
> -------------------------------
>
> Key: HIVE-18786
> URL: https://issues.apache.org/jira/browse/HIVE-18786
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.3.2
> Reporter: Michael Bieniosek
> Priority: Major
>
> When I run a Hive query with windowing functions, if there's enough data I get an NPE.
> For example something like this query might break:
> select id, created_date, max(created_date) over (partition by id) latest_created_any from ...
> The only workaround I've found is to remove the windowing functions entirely.
> The stacktrace looks suspiciously similar to +HIVE-15278+, but I'm in hive-2.3.2 which appears to have the bugfix applied.
