---------------------------------------
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)
