Re: kerberos for outside threads
Hi Koert,

I'm wondering what is the end-to-end goal you want to achieve.

You can disable security in Hadoop, where the cluster does not perform
additional authentication. Obviously you can go without kerberos in this
case and protect your clusters with other measures you've mentioned.

Alternatively, you can enable security without kerberos by plugging in your
own authentication filter.
