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

Fwd: Rebalance topology throws java.lang.StringIndexOutOfBoundsException:
String index out of range: -1
Posted by Spico Florin <sp...@gmail.com>.
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
