    Description

      JobInProgress doesnt maintain any structure for running tasks if speculation is turned off. getRunningMapCache() in JobInProgress exposes the running map cache. This api returns an empty Map if speculation turned off.

      Usage :
      CapicityScheduler requires a list of running tasks for both speculated and non-speculated jobs. See HADOOP-4558 to see how this issue affects CapacityScheduler.
