             Summary: NodeManager still reports negative running containers
                 Key: YARN-4408
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.4.0
            Reporter: Robert Kanter
            Assignee: Robert Kanter

YARN-1697 fixed a problem where the NodeManager metrics could report a negative 
number of running containers.  However, it missed a rare case where this can 
still happen.

YARN-1697 added a flag to indicate if the container was actually launched 
({{LOCALIZED}} to {{RUNNING}}) or not ({{LOCALIZED}} to {{KILLING}}), which is 
then checked when transitioning from {{CONTAINER_CLEANEDUP_AFTER_KILL}} to 
{{DONE}} and {{EXITED_WITH_FAILURE}} to {{DONE}} to only decrement the gauge if 
we actually ran the container and incremented the gauge .  However, this flag 
is not checked while transitioning from {{EXITED_WITH_SUCCESS}} to {{DONE}}.
