[jira] [Created] (HADOOP-10848) Cleanup calling of sun.security.krb5.Config

Kai Zheng created HADOOP-10848:
----------------------------------

             Summary: Cleanup calling of sun.security.krb5.Config
                 Key: HADOOP-10848
                 URL: https://issues.apache.org/jira/browse/HADOOP-10848
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Kai Zheng
            Priority: Minor


As was told by Max (Oracle), JDK9 is likely to block all accesses to sun.* classes.

In ./hadoop-common-project/hadoop-auth/src/main/java/org/apache/hadoop/security/authentication/util/KerberosUtil.java,

sun.security.krb5.Config is called against the method getDefaultRealm() to get default Kerberos realm. It was proposed to remove the call by Oracle:
{code}
new javax.security.auth.kerberos.KerberosPrincipal("dummy").toString().split("@")[1]
{code}
