This can be done in Job client itself, no? History url is already available in
JobStatus.

While the history file name may be available through JobStatus, the history
file is owned by user who runs the job tracker. However access to history file
should be governed by JobACL.VIEW_JOB. Hence the request to have a separate
servlet to provide job history file contents.
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.
