Todd Lipcon commented on HADOOP-7211:
-------------------------------------

HADOOP-6941 fixed compilation on the IBM JDK using reflection, but added some code which definitely does not work - eg:
{code}
      if (System.getProperty("java.vendor").contains("IBM")) {
        principalClass = Class.forName("com.ibm.security.krb5.PrincipalName");
        
        credentialsClass = Class.forName("com.ibm.security.krb5.Credentials");
        krb5utilClass = Class.forName("com.ibm.security.jgss.mech.krb5");
{code}

but the krb5utilClass here is invalid, and there doesn't appear to be any equivalent in the IBM JDK. Instead of this code which kind of looks like it should work, we should just throw an UnsupportedOperationException until someone actually fixes this.

> The security code uses the KrbException, Credentials, and PrincipalName classes from sun.security.krb5 and Krb5Util from sun.security.jgss.krb5. These may disappear in future Java releases. Also Hadoop does not compile using jdks that do not support them, for example with the following IBM JDK.
