Amareshwari Sriramadasu commented on MAPREDUCE-1941:
----------------------------------------------------

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

> 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.
