Hi Bhavesh Shah , thanks for you reply but the this is ,
my Mapper is sending *context.write(new Text(catagoryAll), new IntWritable(val));* and my reducer is like *context.write(key,new IntWritable(sum));* * * and these provide result like hive 1 hadoop 2 and wat i want is output like hive,1 hadoop,2 hope i m able to make u understand so how can i set this in mapper or reducer.
