ml.shifu.guagua.mapreduce.GuaguaOutputFormat

public class GuaguaOutputFormat
extends org.apache.hadoop.mapreduce.OutputFormat<org.apache.hadoop.io.Text,org.apache.hadoop.io.Text>

This is for internal use only. In guagua framework, we don't use mapreduce output format, so this is empty implementation.
