> I set `dfs.nameservices` with the value of one name service (let’s say `ns1` for simplicity) and forgot to set `dfs.namenode.rpc-address.ns1`.
> Then I got an error message:
> {code:java}
> [ERROR] testNonFederation(org.apache.hadoop.hdfs.tools.TestGetConf) Time elapsed: 0.195 s <<< ERROR!
> java.io.IOException: Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.

> The error message above told me that `dfs.namenode.rpc-address` or `dfs.namenode.servicerpc-address` should be set.
> However, the actual reason for the error is that `dfs.namenode.rpc-address.ns1` or `dfs.namenode.servicerpc-address.ns1` is not set.
>
> *How to improve*
> I wrote a patch to improve the error message. Here is the current error message:
> {code:java}
> [ERROR] testNonFederation(org.apache.hadoop.hdfs.tools.TestGetConf) Time elapsed: 0.195 s <<< ERROR!
> java.io.IOException: Incorrect configuration: namenode address dfs.namenode.servicerpc-address[.$NAMESERVICE] or dfs.namenode.rpc-address[.$NAMESERVICE] is not configured.
> {code}
> Then the users can immediately know that they should set `dfs.namenode.rpc-address.ns1` or `dfs.namenode.servicerpc-address.ns1` according to the error message.
