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.
