          Base class for Composite joins returning Tuples of arbitrary Writables.
 class MultiFilterRecordReader<K extends WritableComparable,V extends Writable>
          Base class for Composite join returning values derived from multiple sources, but generally not tuples.
 class OuterJoinRecordReader<K extends WritableComparable>
          Full outer join.
 class OverrideRecordReader<K extends WritableComparable,V extends Writable>
          Prefer the "rightmost" data source for this key.
