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.
