> In very busy clusters we would like to retain applications longer so that users' links
will not expire too soon.  Very often links to application history expire before they can
be followed.
> Simply increasing max-completed applications has an adverse performance impact on the
applications list in the web UI because it presents the entire list of applications with a
request.
> Therefore, we would like some way to be able to increase the retention of applications
without increasing the number of applications sent to the Web UI.
