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

> Components: jobtracker
> Affects Versions: 0.22.0

>
> 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.
