                 URL: https://issues.apache.org/jira/browse/YARN-4093

          Components: api, yarn
            Reporter: Robert Grandl
            Assignee: Robert Grandl


In this JIRA we propose to enhance the AM RM protocol with a new message which 
encapsulates additional  information about group of tasks. The RM scheduler 
will benefit of the additional information to take better decisions at the 
scheduling time.
