> Currently the JobTracker serves the JobHistory to end-users off files
> local-disk/hdfs. While running very large clusters with a large user-base
> might result in lots of traffic for job-history which needlessly taxes the
> JobTracker. The proposal is to have an optional daemon which handles serving
> of job-history requests.
