      Description

      Since we operate many queues pretty much at their capacity it some times happens that a failed mapper causes a reducer ramp down. However, the user can only see "Container killed by the ApplicationMaster" as a diagnostic message for the task attempt, and have to dig through the AM log in order to piece things together.
