> 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.
