`show config file` in cli causes server to throw NPE
-----------------------------------------------------
Key: CASSANDRA-129
URL: https://issues.apache.org/jira/browse/CASSANDRA-129
Project: Cassandra
Issue Type: Bug
Environment: OS X, Java 1.7 (via soylatte)
Reporter: Jeff Hodges
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
