             Summary: Hadoop Kerberos broken on macos as java.security.krb5.realm is reset
                 Key: HADOOP-15966
                 URL: https://issues.apache.org/jira/browse/HADOOP-15966
             Project: Hadoop Common
          Issue Type: Bug
          Components: scripts
    Affects Versions: 3.0.3
            Reporter: Steve Loughran
            Assignee: Steve Loughran
         Attachments: HADOOP-15966-001.patch

HADOOP-8719 may have been valid at some point, but since then the world has moved on

* nobody should be using Hadoop without Kerberos
* kerberos support on java 8 + macos works just fine

The clause to reset the java system properties is enough to stop kerberos working, even
when the user is kinited in.

Propose: remove/revert the changes. If people want it, they can set the options in {{HADOOP_CLIENT_OPTS}}
