>
> {{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}}.
