Matei Zaharia commented on MAPREDUCE-725:
-----------------------------------------
Is it possible to add a hasSpeculativeTask method in JobInProgress rather than
copying it out into the capacity scheduler again?
> CapacityScheduler.TaskSchedulingMgr.hasSpeculativeTask bypasses HADOOP-2141
> ---------------------------------------------------------------------------
