Description

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
