> BucketizedHiveInputFormat doesn't account for ACID

> Key: HIVE-19447
> URL: https://issues.apache.org/jira/browse/HIVE-19447
> Project: Hive
> Issue Type: Bug
> Reporter: Sergey Shelukhin
> Priority: Major
>
> See the TODO added in HIVE-19312.
> It doesn't account for MM tables and can apparently be used for them,
> producing incorrect results.
> I'm not sure if it can be used for ACID tables; we need to fix it for ACID
> (w.r.t. the ACID-related logic in HIF) or perhaps add a negative test where
> for the same query it's used for a non-ACID table but not used for an ACID
> table. mm_bhif test has a simple example query (count distinct iirc)
