John Vines commented on ACCUMULO-1028:
--------------------------------------
By making Accumulo itself agnostic to any sort of Token types it provides more
flexibility to the types of tokens needed, because then there is no need for
them to follow a strict serialization/deserialization interface.
> Distinguish the user principal from the authentication token

> Key: ACCUMULO-1028
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1028
> Project: Accumulo
> Issue Type: Sub-task
> Components: master, tserver
> Reporter: Christopher Tubbs
> Fix For: 1.5.0

>
> The user principal is something that uniquely identifies a user. An
> authentication token is the item that authenticates the user principal, may
> be temporal, and may vary. It is not clear from the implementation of
> ACCUMULO-259 that these are separate things, and I think it would benefit the
> API to distinguish them.
> It could also simplify the API, for users transitioning from the old
> authentication stuff to the new authentication stuff, because there would be
> a one-to-one mapping with the username/password with which they are familiar:
> {code:java}
> public Connector getConnector(String username, byte[] password);
> {code}
> becomes
> {code:java}
> public <T extends AuthToken> Connector getConnector(Principal userPrincipal,
> T authToken);
> {code}
