> TaskAttemptImpl calls RackResolver once for every split location. This results in many shells being spawned by the Application Master when the topology script is enabled. The worst case scenario would entail one call to the topology script for each Datanode. The NameNode is also topology aware, and uses batch calls to the topology script to improve performance.
