    Description

      Currently in pipes, org.apache.hadoop.mapred.pipes.PipesMapRunner.run(RecordReader<K1, V1>, OutputCollector<K2, V2>, Reporter) we do the following:

              while (input.next(key, value)) {
                downlink.mapItem(key, value);
                if(skipping) {
                  downlink.flush();
                }
              }
      

      This would result in consumption of all the records for current task and taking task progress to 100% whereas the actual pipes application would be trailing behind.
