In the following snippet, it tries to get the server principal from the URL.If
we pass IP "KerberosAuthenticator.this.url.getHost()" will not resolved and
it's gives "HTTP/_HOST".
{code:java}
String servicePrincipal = KerberosUtil.getServicePrincipal("HTTP",
KerberosAuthenticator.this.url.getHost());
{code}
was (Author: ranith):
When we are trying to access the webhdfs with IP:port, it is not able to
resolve the HTTP/_HOST PRINCIPAL.
