> 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.
> java.lang.NullPointerException
> at java.io.FileInputStream.<init>(FileInputStream.java:133)
