Subject [jira] [Commented] (HIVE-3072) Hive List Bucketing - DDL support
Date Tue, 14 Aug 2012 03:55:38 GMT


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.
