Amar Kamat commented on HADOOP-4934:
------------------------------------

I propose :
# Allow users to group/browse jobs based on various parameters like time(month/week/day/hour), user, jobname. One way to do it is to store job history files under the user folder, grouped by date instead of storing it in a flat structure. So a user a will have the jobhistory files as _job-history-folder/user-name/day/job-history-file_. This will help when there are too many files in the jobhistory folder.
# Running/Pending/Killed/Failed jobs should not be shown as there is no point to show it in history. One optimization in the above approach would be to have a 3rd level of hierarchy in terms of job state. So a running job history file will be stored as _job-history-folder/user-name/day/running/job-history-file_
# By default show last 100 jobs and allow users to change this value via the web-ui

> It would be nice to group jobs in jobtracker's history based on their completion status.
