Re: org.apache.hadoop.io.serializer.SerializationFactory.getSerializer(SerializationFactory.java:73

Just ran into this myself.  Turns out that your Split object gets created on
the job master node, and needs to get serialized around to workerbee nodes. 
Thus, your split type needs to implement Writable.  See
.../src/mapred/org/apache/hadoop/mapreduce/lib/input/FileSplit.java for an
example.
