> [~ctubbsii], [~kturner] and I hashed out details for best approach for generic tokens
which should work both for our API and the proxy.
> # Client requests the Authenticator class name
> # Client creates instance of Authenticator, calls login(Properties)
> # Properties are used to create the appropriate Token, which implements Writable, and
return it to user.
> # Client uses principal + Token with getConnector call
> # Token is immediately serialized to be used within client api and packaged into a Credential
object
> # Credential gets sent to server via thrift
> # Principal is checked, if !SYSTEM treated as a PasswordToken, otherwise deserialized
as a class defined by the Authenticator (Writable's readFields method called on said class)
> # Token us then passed through the SecurityOperations impl as well as the authenticator
api.
> This allows the authenticator API to use their requested tokens without confusion/code
injection issues with deserialization happening for unknown token classes.
> The exact same process for token creation can also be used by the Proxy, with a Map of
properties being passed it to create a token on the proxy.
> For backward support, the ZKAuthenticator will expect a PasswordToken, which is simply
a byte array.
