Subject [jira] Created: (MAPREDUCE-1073) Progress reported for pipes tasks is incorrect.
Date Wed, 07 Oct 2009 08:28:31 GMT
Progress reported for pipes tasks is incorrect.

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

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) {

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.
