Alexander Pivovarov updated HIVE-7676:
--------------------------------------
Description:
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 0.14.0 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.
