Subject [jira] [Commented] (HIVE-6853) show create table for hbase tables should exclude LOCATION
Date Wed, 09 Apr 2014 05:00:18 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6853?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13963806#comment-13963806
] 

Szehon Ho commented on HIVE-6853:
---------------------------------

Thanks , for the most part it LGTM.  I guess its not the cleanest, as its breaking the StorageHandler
abstraction.  Probably cleaner to add some hook to StorageHandler interface, but due to backward
compatibility, its probably not worth it for this use-case.

+1 (non-binding)

> If you create a table on top of hbase in hive and issue a "show create table <hbase_table>",
it gives a bad DDL. It should not show LOCATION:
