> Previous benchmarks ( HADOOP-2369 , HADOOP-3770 ), while informed by
> production jobs, were principally load generating tools used to validate
> stability and performance under saturation. The important dimensions of that
> load- submission order/rate, I/O profile, CPU usage, etc- only accidentally
> match that of the real load on the cluster. Given related work that
> characterizes production load ( MAPREDUCE-751 ), it would be worthwhile to
> use mined data to impose a corresponding load for tuning and guiding
> development of the framework.
> The first version will focus on modeling task I/O, submission, and memory
> usage.
