Here is an update -\> I have the following modifications (yes its still messy, but you will get the idea) to get me to the point where I get another known error:

And now when I run the webhdfs plugin I get the same error as this [post](https://discuss.elastic.co/t/logstash-webhdfs-example-with-kerberos-enabled-hadoop-cluster/51941) (that has an _interesting_ solution that I am trying now. If this does not work I have to punt, and would advise logstash staff to include this thread in their docs (in some different format), because this is not working with defined gssapi directions.
