I have written the following code

Map:

import java.io.IOException; import java.util.StringTokenizer; import org.apache.hadoop.io.IntWritable; import org.apache.hadoop.io.LongWritable; import org.apache.hadoop.io.Text; import org.apache.hadoop.mapreduce.Mapper; public class Map extends Mapper<LongWritable, Text, Text, IntWritable>{ private IntWritable max = new IntWritable(); private Text word = new Text(); @Override protected void map(LongWritable key, Text value, Context context) throws IOException, InterruptedException { StringTokenizer line = new StringTokenizer(value.toString(),",\t"); word.set(line.nextToken()); max.set(Integer.parseInt(line.nextToken())); context.write(word,max); } }
