      When using a "ReversedType" comparator for a Cassandra keyspace, the following error occurs on a Cassandra Input step:

      Cassandra Input.0 - ERROR (version, build 1 from 2013-09-11_16-51-19 by buildguy) : Unexpected error
      Cassandra Input.0 - ERROR (version, build 1 from 2013-09-11_16-51-19 by buildguy) : org.pentaho.di.core.exception.KettleException:
      2013/11/05 16:22:35 - Cassandra Input.0 -
      2013/11/05 16:22:35 - Cassandra Input.0 - Cant find a deserializer for type "



      Reproduction steps:

      Create table with CQL3:

      create table cf_topher(id int primary key, location text, created 'ReversedType(org.apache.cassandra.db.marshal.DateType)');
      insert into cf_topher(id, location, created) values (123, 'here', '2013-1-1');

      Then point the cassandra input step at this table. Without the 'ReversedType' it works fine. With the type id does not.

      Attaching screen shots for reference.
