Subject Using RowMutations with super columns
Date Wed, 30 Mar 2011 17:54:03 GMT

I'm using (
as base to build a bulk loader. Everything works fine for standard column families but it
fails when trying to insert data in super columns throwing this exception:

Exception in thread "main" java.lang.UnsupportedOperationException: This operation is not
supported for Super Columns.

                at org.apache.cassandra.db.ColumnFamilySerializer.serializeWithIndexes(

Any idea here?

Thank you,
