inherit the original owner of the table.
[ https://issues.apache.org/jira/browse/HIVE-2268?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Esteban Gutierrez updated HIVE-2268:
------------------------------------
Component/s: Security
Description:
When a new table is created by using CREATE.. TABLE.. LIKE.. the new table inherits the existing owner of the table, this is issue is potentially conflicting for multiuser environments where Hive authorization is planned for future use.
-- alice creates table
CREATE EXTERNAL TABLE foo(bar double)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n'
STORED AS TEXTFILE LOCATION '/user/alice/foo';
-- table owner is alice as expected
hive> DESCRIBE EXTENDED foo;
OK
