[jira] Created: (MAPREDUCE-1702) CPU/Memory emulation for GridMix3

CPU/Memory emulation for GridMix3
---------------------------------

                 Key: MAPREDUCE-1702
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1702
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: contrib/gridmix
            Reporter: Jaideep
            Priority: Minor


Currently GridMix3 can successfully recreate I/O workload of jobs from job traces. The goal of this feature is to emulate CPU and memory usage of jobs as well. For this we need to record cpu/memory usage of tasks on the cluster, save them to JobHistory so that they can be read by Rumen, and replay the cpu and memory usage in gridmix3 jobs.
