    Description

      YARN-4459 reduced the chance of the container-executor accidentally killing the wrong process when pids are recycled, but it can still occur. We should improve the DelayedProcessKiller to cancel the timer if the container exits between the deliverly of the two signals and/or implement some sanity checks in the executor just before delivering the signal to try to avoid killing the wrong thing.
