    Description

      Due to the AbstractYarnScheduler#getSchedulerNode method return the generic type, so I think don't need explicit type. 

      I found this issue in CapacityScheduler class. The warning message like:

      Casting 'getSchedulerNode( nonKillableContainer.getAllocatedNode())' to 'FiCaSchedulerNode' is redundant
