Detection of actually execution time

Hi,
Is there any way to detect the duration between the time when all the
map tasks have been assigned to a machine and the time when all the
reduce tasks finish?

Currently, I can only track the duration for JobClient.runJob(jobConf)
to run. But that duration includes the pending time when there is no
available machines in the cluster.

Regards,

Lei
