---------------------------------------

I've talked with Shingo Furuyama and he has taken over this jira.
Could someone assign to him?

> The following code in Client#getRemotePrincipal NPEs if security is enabled and dfs.https.address,
dfs.secondary.http.address, dfs.secondary.https.address, or fs.default.name, has an invalid
value (eg hdfs://foo.bar.com.foo.bar.com:1000). We should check address.checkAddress() for
null (or check this earlier)  and give a more helpful error message.

>   return SecurityUtil.getServerPrincipal(conf.get(serverKey), address
>     .getAddress().getCanonicalHostName());
