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

             Summary: KerberosName.rules are not initialized during adding kerberos support
to a web servlet using hadoop authentications
                 Key: HADOOP-9679
                 URL: https://issues.apache.org/jira/browse/HADOOP-9679
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 2.0.4-alpha, 1.1.2
            Reporter: fang fang chen


I am using hadoop-1.1.1 to add kerberos authentication to a web service. But found rules are
not initialized, that makes following error happened:
java.lang.NullPointerException
        at org.apache.hadoop.security.KerberosName.getShortName(KerberosName.java:384)
        at org.apache.hadoop.security.authentication.server.KerberosAuthenticationHandler$2.run(KerberosAuthenticationHandler.java:328)
        at org.apache.hadoop.security.authentication.server.KerberosAuthenticationHandler$2.run(KerberosAuthenticationHandler.java:302)
        at java.security.AccessController.doPrivileged(AccessController.java:310)
        at javax.security.auth.Subject.doAs(Subject.java:573)
        at org.apache.hadoop.security.authentication.server.KerberosAuthenticationHandler.authenticate(KerberosAuthenticationHandler.java:302)
        at org.apache.hadoop.security.authentication.server.AuthenticationFilter.doFilter(AuthenticationFilter.java:340)

Seems in hadoop-2.0.3, this issue still is not fixed.
