----------------------------------

             Summary: Hive List Bucketing - Query logic
                 Key: HIVE-3554
                 URL: https://issues.apache.org/jira/browse/HIVE-3554
             Project: Hive
          Issue Type: New Feature
            Reporter: Gang Tim Liu


This is part of efforts for list bucketing feature: https://cwiki.apache.org/Hive/listbucketing.html

This patch includes:
1. Query logic: hive chooses right sub-directory instead of partition directory.
2. alter table grammar which is required to support query logic

This patch doesn't include list bucketing DML. Main reasons:
1. risk. w/o DML, this patch won't impact any existing hive regression features since no touch
on any data manipulation.
2. manageability. w/ DML, patch is getting bigger and hard to review

We still disable hive feature by default since DML is not in yet.

DML will be in follow-up patch.
