      Description

      The command in MAPREDUCE-3124 run and this job got hung with 1 Map task waiting for resources and 7 Reducers running (2 waiting). The mapper got scheduler, then AM scheduled the reducers, the map task failed and tried to start a new attempt but reducers were using all the slots.

      I will try to add some more info from the logs.

        I didn't see any reference to lost/removed nodes in the RM log. Looking at the other logs to see if I can get anymore useful info on this.

        Thomas, could glean anything from the logs?

        Also, can you check if any NM was 'lost' i.e. crashed - there is corner-case with headroom calculations when cluster-capacity changes, I'm wondering if that was the cause here?
