> ApplicationCleaner today deletes the entry for all finished (non-running) application in YarnRegistry using this logic:
> # GPG gets the list of running applications from Router.
> # GPG gets the full list of applications in registry
> # GPG deletes in registry every app in 2 that’s not in 1
> The problem is that jobs that started between 1 and 2 meets the criteria in 3, and thus get deleted by mistake. The fix/right order should be 2->1->3, rather than 1->2->3.
