Translate Principal Names from the Active Directory Realm to the MIT Realm

To translate the principal names from the Active Directory realm into local names within the Hadoop cluster, you must configure the hadoop.security.auth_to_local property in the core-site.xml file and hadoop.kms.authentication.kerberos.name.rules property in the kms-site.xml file on all the machines in the Hadoop cluster.

For example, set the following property in core-site.xml on all the machines in the Hadoop cluster:

<property>
  <name>hadoop.security.auth_to_local</name>
  <value>
    RULE:[1:$1@$0](^.*@INFA-AD-REALM$)s/^(.*)@INFA-AD-REALM$/$1/g
    RULE:[2:$1@$0](^.*@INFA-AD-REALM$)s/^(.*)@INFA-AD-REALM$/$1/g
    DEFAULT
  </value>
</property>

For example, set the following property in kms-site.xml on all the machines in the Hadoop cluster:

<property>
  <name>hadoop.kms.authentication.kerberos.name.rules</name>
  <value>
    RULE:[1:$1@$0](^.*@INFA-AD-REALM$)s/^(.*)@INFA-AD-REALM$/$1/g
    RULE:[2:$1@$0](^.*@INFA-AD-REALM$)s/^(.*)@INFA-AD-REALM$/$1/g
    DEFAULT
  </value>
</property>
