> 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.
