> 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.
