> The ResourceManager holds onto a configurable number of completed applications (yarn.resource.max-completed-applications,
defaults to 10000), and the memory footprint of these completed applications can be significant.
 For example, the {{submissionContext}} in RMAppImpl contains references to protocolbuffer
objects and other items that probably aren't necessary to keep around once the application
has completed.  We could significantly reduce the memory footprint of the RM by releasing
objects that are no longer necessary once an application completes.
