Need a servlet in JobTracker to stream contents of the job history file
-----------------------------------------------------------------------

                 Key: MAPREDUCE-1941
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1941
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: jobtracker
    Affects Versions: 0.22.0
            Reporter: Srikanth Sundarrajan
            Assignee: Srikanth Sundarrajan


There is no convenient mechanism to retrieve the contents of the job history file. Need a
way to retrieve the job history file contents from Job Tracker. 

This can perhaps be implemented as a servlet on the Job tracker.

* Create a jsp/servlet that accepts job id as a request parameter
* Stream the contents of the history file corresponding to the job id, if user has permissions
to view the job details.
