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.
