[Hadoop-common-user] Get the number of map & reduce tasks

Hello,

Is it possible to get the actual numbers of map and reduce tasks from the
level of JobClient or RunningJob?

Jobtracker webapp gets this information directly from JobTracker using
JobInProgress class (desiredMaps and desiredReduces), but is it possible to
retrieve this information from client perspective, when the job is submitted
successfully?

Thanks,
x
