I am using current storm/master (ie, 0.11.0-SNAPSHOT). My Python is
2.7.9 (I am using Debian Jessy). Using OpenJDK 1.7.0_79.

About pom.xml: I am aware, that the environments are different and it
makes sense for cluster deployment to set scope to "provided". I just
claim, that this information should be on the web page. ;)

Of even better, your fix, using maven-shade-plugin, should be commited. :)

Here is the correct error message:

> java.lang.RuntimeException: backtype.storm.multilang.NoOutputException: Pipe 
> to subprocess seems to be broken! No output read.
> Serializer Exception:
> Traceback (most recent call last):

> AttributeError: 'module' object has no attribute 'BasicBolt'

Thanks in advance!
