> 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.
