> 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 so that very low risk.
> 2. manageability. w/ DML, patch is getting bigger and hard to review. Removing DML, it's easy to review.
> We still disable hive feature by default since DML is not in yet.
> DML will be in follow-up patch.
