org.kitesdk.data.mapreduce
Class DatasetKeyOutputFormat<E>

java.lang.Object
  org.apache.hadoop.mapreduce.OutputFormat<E,Void>
      org.kitesdk.data.mapreduce.DatasetKeyOutputFormat<E>

Type Parameters:

E - The type of entities in the Dataset.

@Beta
public class DatasetKeyOutputFormat<E>
extends OutputFormat<E,Void>

A MapReduce OutputFormat for writing to a Dataset. Since a Dataset only contains entities (not key/value pairs), this output format ignores the value.
