> We can use beeline as a JDBC client to access RDBMS such as Oracle. Sometimes
> Oracle JDBC driver will return a CLOB object instead of a String object if
> the string is too long. Beeline used to work well with CLOB type but it's
> broken by HIVE-14786:
> [https://github.com/apache/hive/blob/2a760dd607e206d7f1061c01075767ecfff40d0c/beeline/src/java/org/apache/hive/beeline/Rows.java#L169]
> In the above line, when Oracle JDBC driver returns a CLOB object, it returns
> a string like "oracle.sql.CLOB@2f7c7260". In this case, we should use
> ResultSet.getString() rather than ResultSet.getObject().toString().
