Description

Somewhat amusingly, it looks like my NPE on startup is the result of a copy-paste error in:

[clockfort@clockfort cassandra]$ git log --stat 3e5edb82

Fatal error during configuration loading; unable to start. See log for stacktrace.

This is with a cassandra.yaml config snippet of:

start_rpc: true
# rpc_address: localhost
rpc_interface: eth0
# RPC address to broadcast to drivers and other Cassandra nodes. This cannot
# be set to 0.0.0.0. If left blank, this will be set to the value of
# rpc_address. If rpc_address is set to 0.0.0.0, broadcast_rpc_address must
# be set.
# broadcast_rpc_address: 1.2.3.4
