Chris Riccomini commented on SAMZA-589:
---------------------------------------

bq. Still, our concern is at least partly about having the values logged at all 

I agree, it's a bit sketchy. Masking, at a minimum, would help.

> Currently, the full contents of a job's Config is exposed in at least a 
> couple of places including the logs (logged by SamzaContainer), and the 
> ApplicationMaster UI's config page.  There is a security concern with doing 
> that if sensitive information (e.g. credentials) is stored there.  It would 
> be nice to be able to mark sensitive config values so that they are not 
> displayed in such ways.  The only thing that springs to mind is a special 
> naming convention, perhaps a "sensitive" prefix that would identify these 
> values.  Ideally such a capability would be baked into Config itself, but 
> minimally Samza code that exposes Config could be made aware of the 
> convention to avoid displaying the plaintext of sensitive values.
