chance of not updating progress and timing out

                 Key: HADOOP-1983
                 URL: https://issues.apache.org/jira/browse/HADOOP-1983
             Project: Hadoop
          Issue Type: Bug
          Components: pipes
    Affects Versions: 0.15.0
            Reporter: Christian Kunz


When using C++-pipes interface, mappers/reducers not emitting any key-values 
pairs, but running longer than 'mapred.task.timeout' might timeout even when 
they send periodical status updates upstream.

The cause of the problem is that all upstream messages are buffered. Progress 
and status updates should be flushed immediately.
