----------------------------------
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.
