-----------------------------------------
Summary: 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
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 show 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.
