> We have a custom snitch that works in 1.1, but the same does not work in 1.2
> . It throws a ConfigurationException:
> {panel}
> ERROR 11:39:37,936 Fatal configuration error
> org.apache.cassandra.exceptions.ConfigurationException: Unable to find snitch
> class 'com.apigee.cassandra.OldEC2Snitch'

> However the above exception does not help us understand what's wrong (jar is
> in the classpath and readable). I've to add the root clause to the
> ConfigurationException to see the real problem:
