[jira] Created: (MAPREDUCE-1941) Need a servlet in JobTracker to
stream contents of the job history file
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.

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.
