>                 Key: MAPREDUCE-1073
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1073
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: pipes
>    Affects Versions: 0.20.1
>            Reporter: Sreekanth Ramakrishnan
>
> 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.
