[jira] [Created] (HIVE-19447) BucketizedHiveInputFormat doesn't account for ACID

Sergey Shelukhin created HIVE-19447:
---------------------------------------

             Summary: 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


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)
