Add support to turn off bucketing with ALTER TABLE
--------------------------------------------------
Key: HIVE-1443
URL: https://issues.apache.org/jira/browse/HIVE-1443
Project: Hadoop Hive
Issue Type: Improvement
Reporter: Paul Yang
Assignee: Paul Yang
Fix For: 0.7.0
Currently, there is an alter table command that can change the bucketing / sort
columns, as well as the number of buckets (ALTER TABLE table_name CLUSTERED BY
(col_name, col_name, ...) [SORTED BY (col_name, ...)] INTO num_buckets
BUCKETS). However, this command does not provide a means to disable bucketing.
This proposes to introduce a syntax like
ALTER TABLE src NOT CLUSTERED;
that would turn off bucketing.
