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.
