> As applications complete, the RM tracks their IDs in a completed list. This
> list is routinely truncated to limit the total number of application
> remembered by the RM.
> When a user clicks the History for a job, either the browser is redirected to
> the application's tracking link obtained from the stored application
> instance. But when the application has been purged from the RM, an error is
> displayed.
> In very busy clusters the rate at which applications complete can cause
> applications to be purged from the RM's internal list within hours, which
> breaks the proxy URLs users have saved for their jobs.
> We would like the RM to provide valid tracking links persist so that users
> are not frustrated by broken links.
