Description

Booting up the cli and running the command "show config file" in the lastest from trunk (r771019) on a fresh and empty cassandra instance causes a NullPointerError to be thrown. By looking at the code (but being a not-so-hot java developer), it looks like the problem is simply DatabaseDescriptor.getConfigFileName() returning a null because configFileName_ never gets set anywhere in the code.

The error in question:

ERROR - Error occurred during processing of message.
