> 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}
