    Description

      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.
