Sharad Agarwal updated MAPREDUCE-817:
-------------------------------------
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. (was: 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.)
