      Description

      Hadoop has long maintained its own configuration for Kerberos' auth_to_local rules. To the user this is counter intuitive and increases the complexity of maintaining a secure system as the normal way of configuring these auth_to_local rules is done in the site wide krb5.conf usually /etc/krb5.conf.

      With HADOOP-15996 there is now support for configuring how Hadoop should evaluate auth_to_local rules. A "system" mechanism should be added.

      It should be investigated how to properly parse krb5.conf. JDK seems to be lacking as it is unable to obtain auth_to_local rules due to a bug in its parser. Apache Kerby has an implementation that could be used. A native (C) version is also a possibility.
