> Hello!
> In the mentioned version for Windows, the rebalance command arguments should
> not be passed as indicated in
> https://github.com/nathanmarz/storm/wiki/Understanding-the-parallelism-of-a-Storm-topology
> storm rebalance mytopology -n 5 -e blue-spout=3 -e yellow-bolt=10
> In order to get rid of the mentioned
> exception(java.lang.StringIndexOutOfBoundsException:) you should use the
> command
>
> storm rebalance WordCount -e "spout=3"
> However, trying to rebalance more components (either spouts or bolts) will
> rebalance only the latest component mentioned in the list. So, for example
> for example:
> storm rebalance WordCount -e "spout=3" -e "count=5"
> the rebalance will be applied only for the "count" component not for the
> "spout".
> So, in my opinion either the documentation should be updated or the
> rebalance.clj should be changed in order to support rebalancing for multiple
> components.
> I look forward for your opinions.

> Hello!
> I'm using the Taylor Goetz's storm version pointed out by article
> http://ptgoetz.github.io/blog/2013/12/18/running-apache-storm-on-windows/
> and located at:
> https://github.com/ptgoetz/incubator-storm/tree/windows-test
> I have succeeded to install everything on my computer (running windows 7, 64
> bit). I have also ran fine the indicated topology and my topology too. But
> when I'm trying to do a rebalancing of my topology by re-configuring the
> number of spouts or bolt with the command
> storm rebalance WordCount -e spout=3
> I'm getting the exception:
> Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String
> index out of range: -1
> at java.lang.String.substring(String.java:1911)
> at
> backtype.storm.command.rebalance$parse_executor.invoke(rebalance.clj:24)
> at clojure.tools.cli$apply_specs.invoke(cli.clj:80)
> at clojure.tools.cli$cli.doInvoke(cli.clj:130)
> at clojure.lang.RestFn.invoke(RestFn.java:460)
> at backtype.storm.command.rebalance$_main.doInvoke(rebalance.clj:31)
> at clojure.lang.RestFn.applyTo(RestFn.java:137)
> at backtype.storm.command.rebalance.main(Unknown Source)
> If I'm changing only the number of workers it works without any exceptions.
> If someone of you have tested this version, can you please help me to get rid
> of it?
> I'll look forward for your answers.
> Thanks in advance.
