Allen Wittenauer resolved MAPREDUCE-2425. ----------------------------------------- Resolution: Won't Fix closing as won't fix > Distributed simulator for stressing JobTracker and NameNode > ----------------------------------------------------------- > > Key: MAPREDUCE-2425 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-2425 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Components: contrib/mumak > Reporter: Min Zhou > Labels: benchmark, hadoop > Attachments: ASF.LICENSE.NOT.GRANTED--.jpg, > ASF.LICENSE.NOT.GRANTED--screenshot-1.jpg > > > Hadoop need a tool for stressing JobTracker and NameNode. Mumak introduced a > simulated JobTracker, whose behavior doesn't exactly like that of the real > JobTracker. Even more, mumak can't simulate a large cluster with quite a lot > of jobs run on it. On the other hand, Gridmix v3 need hundreds of physical > nodes to replay job stories. > You can think this tool a complementation of mumak and gridmix v3. We > successfully used this tool to simulate a 12000 nodes cluster through 4 real > machines. > I've talk to Hong Tang and Scott Chen offline, they suggested me contributing > this tool to the hadoop community. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
