Hi Tim,
You can write a class inherit from org.apache.hadoop.mapred.lib.
MultipleOutputFormat. Override method generateFileNameForKeyValue() like
this
1. @Override
2. protected
String generateFileNameForKeyValue(K key, V value, String name) {
3. return name + "_" + value.toString();
4. }
you can also check out http://coderplay.javaeye.com/blog/191188 for example.
