    Description

      when the value of NameRules is not configured in Kerberized Environment,
      I start ranger-admin,it will cause java.lang.NullPointerException
      the error message is as follows:

      java.lang.NullPointerException
 at org.apache.hadoop.security.authentication.util.KerberosName.getShortName(KerberosName.java:383)
 at org.apache.hadoop.security.User.<init>(User.java:48)
 at org.apache.hadoop.security.SecureClientLogin.loginUserFromKeytab(SecureClientLogin.java:65)
 at org.apache.ranger.server.tomcat.EmbeddedServer.start(EmbeddedServer.java:232)
 at org.apache.ranger.server.tomcat.EmbeddedServer.main(EmbeddedServer.java:72)

      so we should add the default value in Java method EmbeddedServer.start():

      String nameRules = getConfig(ADMIN_NAME_RULES);
if (getConfig(AUTHENTICATION_TYPE) != null
	&& getConfig(AUTHENTICATION_TYPE).trim().equalsIgnoreCase(AUTH_TYPE_KERBEROS)
	&& SecureClientLogin.isKerberosCredentialExists(principal,keytab)) {
 ...
}
