use of with Isilon


Previously it had always recommended adding the following to the core-site.xml to limit hostname and IP exposure when getting Kerberos delegation tokens: when using Kerberos with HDP and Isilon.

But in recent deployments, this setting does not appear as critical as previously required if full forward and DNS is implemented correctly. (PTR's on all Isilon Pool IP's).

I'm looking for any field experience on this issue, is this setting still required or needed to avoid delegation token issues?
