The org.apache.hadoop.mapreduce Class Mapper<KEYIN,VALUEIN,KEYOUT,VALUEOUT> has an example with public void map(Object key, Text value, Context context) But, "Any type which is to be used as a key in the Hadoop Map-Reduce framework should implement this interface." org.apache.hadoop.io Interface WritableComparable<T> The example has Object for key type.
