Hi Shahab, Thanks for the response.
I have added the @Override and somehow that worked. I have pasted the new Reducer code below. Though, I did not understood the difference here, as if what I have done differently. I might be a very silly reason though. ========================================================= package com.test.hadoop; import java.io.IOException; import org.apache.hadoop.io.IntWritable; import org.apache.hadoop.io.Text; import org.apache.hadoop.mapreduce.Reducer; public class WordCountReducer extends Reducer<Text, IntWritable, Text, IntWritable> { @Override protected void reduce(Text key, Iterable<IntWritable> values, Context context) throws IOException, InterruptedException { int sum = 0; for (IntWritable val : values) { sum += val.get(); } context.write(key, new IntWritable(sum)); } } ========================================================= Regards, Parkirat Bagga. -- View this message in context: http://apache-hbase.679495.n3.nabble.com/Hbase-Mapreduce-API-Reduce-to-a-file-is-not-working-properly-tp4062141p4062240.html Sent from the HBase User mailing list archive at Nabble.com.
