Hmm, this is because MTable now has two LONGVARCHAR fields (viewOriginalText and viewExpandedText). Can you find a way to get the Oracle driver or JDO to map these to CLOB instead of LONG VARCHAR? Oracle allows multiple CLOB fields on the same table, but only one LONG VARCHAR (legacy crud).

You also need to get a copy of the Oracle thin JDBC driver (or some other JDBC driver that supports Oracle) and make sure that it is available in Hive's classpath (e.g. by referencing it in HIVE_AUX_JARS_PATH). If this does not work out of the box I recommend consulting the documentation that comes with your JDBC driver. Thanks.
