                 Key: HADOOP-3001
                 URL: https://issues.apache.org/jira/browse/HADOOP-3001
             Project: Hadoop Core
          Issue Type: New Feature
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley
             Fix For: 0.17.0


It would be nice if the file systems could track the number of bytes read and 
written for each class of FileSystem. Map/Reduce could then report these 
numbers back as counters to provide information about how much data is read and 
written.
