Namit Jain commented on HIVE-3072:
----------------------------------

Also, the DML support would require complete support for running tests on 
hadoop 23 (or some version of hadoop
which has support for nested directories). I know, there are a couple of jiras 
for making it work, like HIVE-3341,
but they are not done yet.
Also, these are independent and we should reduce dependencies on HIVE-3341 as 
far as possible.

> If a hive table column has skewed keys, query performance on non-skewed key 
> is always impacted. Hive List Bucketing feature will address it:

> This jira issue will track DDL change for the feature. It's for both single 
> skewed column and multiple columns.
