> 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.
