Hari Sekhon created HIVE-9576:
---------------------------------
Summary: ALTER TABLE STORED AS - change storage format and/or
compression
Key: HIVE-9576
URL: https://issues.apache.org/jira/browse/HIVE-9576
Project: Hive
Issue Type: New Feature
Affects Versions: 0.14.0
Environment: HDP 2.2
Reporter: Hari Sekhon
Feature request to support rewriting a table into a different format or
compression level via a single alter table statement:
{code}ALTER TABLE ... STORED AS... TBLPROPERTIES(...){code}
Currently we create a new table of a different format and do
{code}INSERT OVERWRITE newtable SELECT * FROM oldtable{code}
but a colleague has just asked me why this can't be handled by a single alter
statement via a tempory table replacement under the hood, which seems like a
fair question.
