             Summary: Ensure not to launch container on blacklisted nodes
                 Key: MAPREDUCE-4599

          Issue Type: Sub-task
          Components: applicationmaster
    Affects Versions: MR-3902
            Reporter: Tsuyoshi OZAWA
            Assignee: Tsuyoshi OZAWA
            Priority: Minor


The current implementation of RMContainerAllocator doesn't ensure not to launch containers
on blacklisted nodes. This may cause some skews by tasks on bad nodes.
