> On the ResourceManager's scheduler web page, the bottom of the page shows the
> apps block. When the cluster has run a lot of applications (e.g.: 10,000+)
> loading the apps table can take a long time, and that prolongs the plotting
> of the queue status which is the most interesting portion of the page.
> If the user is bothering to go to the scheduler page, they're probably not
> interested in apps that are not affecting what the scheduler is doing (e.g.:
> FINISHED, FAILED, KILLED, etc.). Having the RM filter the apps for this page
> should significantly reduce the time it takes to load this page on the
> client, and it also helps reduce the amount of apps the user has to sift
> through when looking for the apps that are affecting what the scheduler is
> doing.
