how to access Mapper Counter value in a Reducer?

Question

I want to acces the myCounter.my value in reducer :

public static class Map extends Mapper

        

Answer 1

You to make it work for new API by accessing the counters via job object.

Configuration conf = context.getConfiguration();
Cluster cluster = new Cluster(conf);
Job currentJob = cluster.getJob(context.getJobID());
long val=currentJob.getCounters().findCounter(myCounter.my).getValue();
