Description

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.
