> Since users would have manually set up the Ambari principal after enabling Kerberos using
{{ambari-server setup-security}} {{option #3}} ("Setup Ambari kerberos JAAS configuration")
in Ambari versions before 2.4.0, there is no need to configure Ambari to automatically manage
its principals after an upgrade to version 2.4.0 and above. 
> Therefore, upon upgrade to Ambari 2.4.0 or above, the upgrade process (in {{UpgradeCatalog240}})
should ensure that "kerberos-env/create_ambari_principal}} is set to "false".  By default
this value will be set to "true" after {{org.apache.ambari.server.upgrade.AbstractUpgradeCatalog#addNewConfigurationsFromXml}}
is executed. 
> Note: This may have an effect on Ambari versions 2.4.2 and above if Kerberos authentication
is enabled and the SPNEGO ({{HTTP/_HOST}}) principal and keytab file is already created and
installed.
