Richard Ding created HIVE-3217:
----------------------------------
Summary: Implement HiveResultSetMetaData.getFunctions() to
retrieve registered UDFs.
Key: HIVE-3217
URL: https://issues.apache.org/jira/browse/HIVE-3217
Project: Hive
Issue Type: Improvement
Components: JDBC
Affects Versions: 0.9.0
Reporter: Richard Ding
Hive JDBC support currently throws UnsupportedException when getFunctions() is
called. Hive CL provides a SHOW FUNCTIONS command to return the names of all
registered UDFs. By getting a SQL Statement from the connection, getFunctions
can execute( "SHOW FUNCTIONS") to retrieve all the registered functions
(including those registered through create temporary function).
