Karthik Kambatla commented on MAPREDUCE-4706:
---------------------------------------------
Verified on a pseudo-distributed cluster that the running maps and running
reduces are being reported. Without this patch, they were zero. The patch uses
{{#getMapSchedulable()}}, {{#getReduceSchedulable()}}, and
{{#getRunningTasks()}} methods - existing tests use this methods and thereby
validate their behavior.
> FairScheduler#dump(): Computing of # running maps and reduces is commented out

> meaningful information.
