Yes , i agree. Since we have already populated {{ApplicationAclManager}}
further the context might not be required.

> 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.
