Subject [jira] [Commented] (ACCUMULO-3045) Support AuthenticationToken backed by CredentialProvider
Date Wed, 06 Aug 2014 03:48:12 GMT

Christopher Tubbs commented on ACCUMULO-3045:
---------------------------------------------

My main concern is information for users. Since you haven't fundamentally altered any internal
code, I don't think this feature adds any significant change that developers should be aware
of.

> Along the same lines as ACCUMULO-2464, the MapReduce AuthenticationToken serialization
also has the potential to be stored in a non-secure form. Some of this is mitigated via Base64
the password to remove human-readable-ness, the ability to serialize an AuthenticationToken
to a file, etc.
> Wiring up a CredentialProvider as an AuthenticationToken is another option provided to
us by Hadoop likely to handle tricky security-related concerns for us.
