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).
