> Project: Hive
> Issue Type: Bug
> Reporter: Ádám Szita
> Assignee: Ádám Szita
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> As discussed in HIVE-25420 time column is not native Hive type, reading it is
> more complicated, and is not supported for vectorized read. Trying this
> currently results in an exception, so we should make an effort to
> * either gracefully fall back to non-vectorized reads when there's such a
> column in the query's projection
> * or work around the reading issue on the execution side.
