             Summary: AppMasterLauncher to use resource limits provided by YARN to fail fast if AM resource ask too big
                 Key: SLIDER-807
                 URL: https://issues.apache.org/jira/browse/SLIDER-807
             Project: Slider
          Issue Type: Improvement
          Components: client
    Affects Versions: Slider 0.70
            Reporter: Steve Loughran
            Assignee: Steve Loughran
            Priority: Minor
             Fix For: Slider 0.80


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

{code}
application = yarnClient.createApplication();
application.getNewApplicationResponse().getMaximumResourceCapability();
{code}

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