> Currently in pipes, {{org.apache.hadoop.mapred.pipes.PipesMapRunner.run(RecordReader<K1, V1>, OutputCollector<K2, V2>, Reporter)}} we do the following:
> {code}
> while (input.next(key, value)) {
> downlink.mapItem(key, value);
> if(skipping) {
> downlink.flush();
> }
> }
> {code}
> 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.
