Key: MAPREDUCE-2599

Project: Hadoop Map/Reduce
Issue Type: Bug
Components: contrib/gridmix
Reporter: Vinay Kumar Thota
Assignee: Amar Kamat
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.
