Gridmix: Trace-based benchmark for Map/Reduce
---------------------------------------------
Key: MAPREDUCE-776
URL: https://issues.apache.org/jira/browse/MAPREDUCE-776
Project: Hadoop Map/Reduce
Issue Type: New Feature
Reporter: Chris Douglas
Assignee: Chris Douglas
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.
