Allen Wittenauer resolved MAPREDUCE-1261. ----------------------------------------- Resolution: Won't Fix > 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? -- This message was sent by Atlassian JIRA (v6.2#6252)
