> {{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}}.
