      Description

      MAPREDUCE-814 will provide a way to keep the job history files in HDFS. There should be a way to get the url for the completed job history fie. The completed jobs can be purged from memory more aggressively from jobtracker since the clients can retrieve the information from history file. Jobtracker can just maintain the very basic info about the completed jobs.
