Jian Fang commented on MAPREDUCE-6304:
--------------------------------------
A more generic way could be to add a decorator to ApplicationSubmissionContext
in class ClientRMService so that people can change the
ApplicationSubmissionContext in the method submitApplication(). The default
decorator from Apache does nothing, but hadoop allows users to use a custom
decorator from hadoop configuration.
