Hi all,
this is my first post on the development list of cassandra - but I think
this belongs here.
I'm running cassandra for a while now, and on testing I ran in many of
2.1.2s issues. So I upgraded my test cluster from 2.1.2 to 2.1.3. I
updated with the debian packages, diffed my cassandra.yaml and applied
our changes to the new cassandra.yaml. Those changes are:
- cluster_name
- seeds
- listen_interface instead of listen_address
- rpc_interface instead of rpc_address
Nothing really spectacular - interface is nice as all nodes have the
same cassandra.yaml. But trying to start 2.1.3 gives me an NPE:
ERROR [main] 2015-02-20 07:50:09,661 DatabaseDescriptor.java:144 - Fatal
error during configuration loading
java.lang.NullPointerException: null

I also tried the .tar.gz distribution with the same result. I looked at
the code of DatabaseDescriptor, and if someone uses rpc_interface this
piece of code is executed:
/* 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();
}
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:
if(rpcAddress.isAnyLocalAddress())
After changing rpc_interface to rpc_address everything works as expected.
Best regards,
Jan
