Brandon Williams resolved CASSANDRA-9208.
-----------------------------------------
Resolution: Duplicate
> Setting rpc_interface in cassandra.yaml causes NPE during startup
> -----------------------------------------------------------------
>
> Key: CASSANDRA-9208
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9208
> Project: Cassandra
> Issue Type: Bug
> Components: Config
> Environment: Windows and RHEL
> Reporter: Sandeep More
> Attachments: SuggestedDataBaseDescriptor.diff
>
>
> In the cassandra.yaml file when "rpc_interface" option is set it causes a NPE
> (stack trace at the end).
> Upon further investigation it turns out that there is a serious problem is in
> the way this logic is handled in the code DatabaseDescriptor.java (#374).
> Following is the code snippet
> else if (conf.rpc_interface != null)
> {
> listenAddress = getNetworkInterfaceAddress(conf.rpc_interface,
> "rpc_interface");
> }
> else
> {
> rpcAddress = FBUtilities.getLocalAddress();
> }
> If you notice,
> 1) The code above sets the "listenAddress" instead of "rpcAddress".
> 2) The function getNetworkInterfaceAddress() blindly assumes that this is
> called to set the "listenAddress" (see line 171). The "configName" variable
> passed to the function is royally ignored and only used for printing out
> exception (which again is misleading)
> I am also attaching a suggested patch (NOTE: the patch tries to address this
> issue, the function getNetworkInterfaceAddress() needs revision ).
