Description

It turns out there's a way to get the information from YARN as to the max resource capabilities before asking for the AM.

application = yarnClient.createApplication();
application.getNewApplicationResponse().getMaximumResourceCapability();

this can be used to validate the resource options before even asking YARN for the application
