        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.

        Uploading a patch that calculates runningMaps and runningReduces before logging them.

        Will run a cluster manually and report.
