Subject Re: exception when running kafka
Date Sun, 09 Sep 2012 04:30:31 GMT
Hi Will,

Thanks! I took a look at bin/kafka_run_class.sh and saw how it builds the
classpath. I then notice that the project/boot did not exist, so I created
it and placed the scala directory into it so that it gets added to the
classpath.

That fixed the problem - it now runs!

Thanks for pointing me in the right direction.

Daniel.
