Subject: Fwd: Rebalance topology throws
java.lang.StringIndexOutOfBoundsException: String index out of range: -1

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.
Regards,
Florin

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.
Regards,
Florin
