-------------------------------------
Summary: DatabaseDescriptor throws NPE when rpc_interface is used
Key: CASSANDRA-8839
URL: https://issues.apache.org/jira/browse/CASSANDRA-8839
Project: Cassandra
Issue Type: Bug
Components: Config
Environment: 2.1.3
Reporter: Jan Kesten
Copy from mail to dev mailinglist.
When using
- listen_interface instead of listen_address
- rpc_interface instead of rpc_address
starting 2.1.3 throws an NPE:
{code}
ERROR [main] 2015-02-20 07:50:09,661 DatabaseDescriptor.java:144 - Fatal error

Occurs on debian package as well as in tar.gz distribution.

/* Local IP, hostname or interface to bind RPC server to */
if(conf.rpc_address !=null&& conf.rpc_interface !=null)
{
throw newConfigurationException("Set rpc_address OR rpc_interface, not
both");
}
else if(conf.rpc_address !=null)
{
try
{
rpcAddress = InetAddress.getByName(conf.rpc_address);
}
catch(UnknownHostException e)
{
throw newConfigurationException("Unknown host in rpc_address "+
conf.rpc_address);
}
}
else if(conf.rpc_interface !=null)
{
listenAddress =
getNetworkInterfaceAddress(conf.rpc_interface,"rpc_interface");
}
else
{
rpcAddress = FBUtilities.getLocalAddress();
}
{code}
I think that listenAddress in the second else block is an error. In my case
rpc_interface is eth0, so listenAddress gets set, and rpcAddress remains unset.
The result is NPE in line 411:
{code}
if(rpcAddress.isAnyLocalAddress())
{code}
After changing rpc_interface to rpc_address everything works as expected.
