Arun Suresh created YARN-3676:

             Summary: Disregard 'assignMultiple' directive while scheduling 
apps with NODE_LOCAL resource requests
                 Key: YARN-3676
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
            Reporter: Arun Suresh
            Assignee: Arun Suresh

AssignMultiple is generally set to false to prevent overloading a Node (for eg, 
new NMs that have just joined)

A possible scheduling optimization would be to disregard this directive for 
apps whose allowed locality is NODE_LOCAL
