> Issue Type: Bug
> Reporter: Jungtaek Lim
> Priority: Minor

> There's one topology in cluster, and it is storm.starter.RollingTopWords from
> storm-starter.
> https://github.com/apache/storm/blob/master/examples/storm-starter/src/jvm/storm/starter/RollingTopWords.java
> I just ran rebalance via REST API, and found something is not working
> properly.
> {noformat}
> curl -X POST -H "Content-Type: application/json" -d '{"rebalanceOptions":
> {"numWorkers": 2, "executors": {"wordGenerator": 10, "counter": 7,
> "intermediateRanker": 10}}}'
> http://localhost:8080/api/v1/topology/production-topology-4-1433927082/rebalance/50
> {noformat}
> It changes number of workers to 2, but it doesn't change any components'
> executor count.
> Sample of rebalance REST API from document is here.
