I'm using the hector 0.8.0-2 against cassandra 0.8.1.

When I executed the code:

rangeSlicesQuery.setColumnFamily(columnFamily).setKeys(key, key)
                .setRange(startColumn, null, reversed, count);

I got the following errors:

Caused by: me.prettyprint.hector.api.exceptions.HCassandraInternalException: Cassandra encountered an internal error processing this request: TApplicationError type: 6 message:Internal error processing get_range_slices

I only got this error when the startColumn is greater than the 'biggest' column in the row.

Is this a bug? Any ideas? 

Thanks.
