> At present, Knox talking to Kerberos protected Hadoop cluster, does SPNegot authentication with Hadodop every request. This is not scalable and needs to be fixed. I think we could cache hadoop.auth cookie returned by Hadoop service and avoid repeating SPNego authentication. Requires more research, tests and some POC.
