> {{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}}.
