Keigun S. Moon created HIVE-3015:
------------------------------------

             Summary: org.apache.hadoop.hive.jdbc.HiveResultSetMetaData.getColumnClassName Method not supported
                 Key: HIVE-3015
                 URL: https://issues.apache.org/jira/browse/HIVE-3015
             Project: Hive
          Issue Type: Wish
          Components: JDBC
    Affects Versions: 0.7.1
         Environment: JDK 1.6, Hadoop 0.20.2-cdh3u3, Hive 0.7.1-cdh3u3, myBatis 3.1.1
            Reporter: Keigun S. Moon


When I use Hive JDBC driver, 
If I call org.apache.hadoop.hive.jdbc.HiveResultSetMetaData.getColumnClassName() method,
it throws exception like this

java.sql.SQLException: Method not supported
	at org.apache.hadoop.hive.jdbc.HiveResultSetMetaData.getColumnClassName(HiveResultSetMetaData.java:47)
	at com.ucloud.log.app.hive.HiveService.main(HiveService.java:54)

I tested hive with myBatis.

When myBatis parsed ResultSet, it used getColumnClassName() method to get column name of Hive Table.

This is unit test error message.
