             Project: Hadoop Map/Reduce
          Issue Type: Bug

Gridmix system test are failing due to misconfiguration of task memory in simulated cluster
when high ram job emulation enabled.

Girdmix scale the task memory for emulation of high ram jobs based on simulated cluster configuration
and it reserved the slots based on scaled memory information of each task. Here, I found an
issue, suppose if total reserved slots of either map or reduce exceeds the slot capacity then
it hangs the job and failed after timeout.So, Gridmix should show either error message or
bailing out before submitting the job in this condition.
