Enhance mumak to implement a 'stress-test' for the JobTracker
-------------------------------------------------------------
Key: MAPREDUCE-1261
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1261
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: contrib/mumak
Reporter: Arun C Murthy
I propose we enhance mumak to implement a proper 'stress-test' tool for the
JobTracker. The idea is that we enhance mumak to have a mode where it can use
the *real* JobTracker (and Scheduler of course) and mumak's
SimulatedTaskTracker to run real workloads from production job-history traces.
Clearly we will need to make necessary changes to allow the
SimulatedTaskTrackers to run independently (a thread per SimulatedTT) in a
distributed manner.
We can then simulate very large clusters and workloads using a handful of
machines (say ~50 machines to simulate workload which originally ran on a 4000
node cluster), also we can use this to stress the JobTracker with synthetic
workloads.
Thoughts?
