Alexander Pivovarov updated HIVE-7676:
--------------------------------------
Attachment: HIVE-7676.patch
> Support more methods in DatabaseMetaData
> ----------------------------------------
>
> Key: HIVE-7676
> URL: https://issues.apache.org/jira/browse/HIVE-7676
> Project: Hive
> Issue Type: Improvement
> Components: JDBC
> Reporter: Alexander Pivovarov
> Attachments: HIVE-7676.patch
>
>
> I noticed that some methods in HiveDatabaseMetaData throws exceptions instead
> of returning true/false. Many JDBC clients expects implementations for
> particular methods in order to work.
> E.g. SQuirreL SQL shows databases only if supportsSchemasInTableDefinitions
> returns true.
> Also hive 0.13.1 supports UNION ALL and does not support UNION
> we can indicate this in HiveDatabaseMetaData instead of throwing Method Not
> supported exception.
> getIdentifierQuoteString should return space if not supported.
