> 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.
