> we are now testing storm-0.9.0.1 cluster for migrating. When running the topologies in storm-starter, such as WordCountTopology, ReachTopology, we found the number of workers, executors, and tasks is unexplainable (according to https://github.com/nathanmarz/storm/wiki/Understanding-the-parallelism-of-a-Storm-topology ):
> 1) WordCountTopology:
> Name Id Status Uptime Num workers Num executors Num tasks
> wc-test3 wc-test3-3-1388986658 ACTIVE 29m 5s 25 50 50
> wc-test2 wc-test2-2-1388986111 ACTIVE 38m 12s 4 29 29
> wc-test wc-test-1-1388981297 ACTIVE 1h 58m 26s 3 28 28
> This topology's configuration is as follows:
> TopologyBuilder builder = new TopologyBuilder();
> builder.setSpout("spout", new RandomSentenceSpout(), 5);
> builder.setBolt("split", new SplitSentence(), 8).shuffleGrouping("spout");
> builder.setBolt("count", new WordCount(), 12).fieldsGrouping("split", new Fields("word"));
> ......
> conf.setNumWorkers(3); #4, 25
> 2) ReachTopology (which is a drpc topology):
> Name Id Status Uptime Num workers Num executors Num tasks
> reach-test reach-test-4-1388986889 ACTIVE 32m 20s 6 35 35
> This topology's configuration is as follows:
> LinearDRPCTopologyBuilder builder = new LinearDRPCTopologyBuilder("reach");
> builder.addBolt(new GetTweeters(), 4);
> builder.addBolt(new GetFollowers(), 12).shuffleGrouping();
> builder.addBolt(new PartialUniquer(), 6).fieldsGrouping(new Fields("id", "follower"));
> builder.addBolt(new CountAggregator(), 3).fieldsGrouping(new Fields("id"));
> ......
> conf.setNumWorkers(6);
