-----------------------------------

             Summary: Fix Opportunistic Scheduling for node local allocations.
                 Key: YARN-9448
                 URL: https://issues.apache.org/jira/browse/YARN-9448
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Abhishek Modi
            Assignee: Abhishek Modi


Right now, opportunistic container might not get allocated on rack local node even if it's
available.

Nodes are right now blacklisted if any container except node local container is allocated
on that node. In case, if previously container was allocated on that node, that node wouldn't
be even considered even if there is an ask for node local request.
