> We've now got some fairly complex auth mechanisms going on: -hadoop config, KMS, env vars, "none". IF something isn't working, it's going to be a lot harder to debug.
> I propose *carefully* adding some debug messages to identify which auth provider is doing the auth, so we can see if the env vars were kicking in, sysprops, etc.
> What we mustn't do is leak any secrets: this should be identifying whether properties and env vars are set, not what their values are. I don't believe that this will generate a security risk.
