             Summary: [Umbrella] Add support for YARN Allocation composed of multiple containers/processes
                 Key: YARN-5593
                 URL: https://issues.apache.org/jira/browse/YARN-5593
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Arun Suresh
            Assignee: Arun Suresh


Opening this to explicitly call out and track some of the ideas that were discussed in YARN-1040. Specifically the concept of an {{Allocation}} which can be used by an AM to start multiple {{Containers}} against as long as the sum of resources used by all containers {{fitsIn()}} the Resources leased to the {{Allocation}}.
This is especially useful for AMs that might want to target certain operations (like upgrade / restart) on specific containers / processes within an Allocation without fear of losing the allocation.
