> It should be possible to externalize the secret used to sign the hadoop-auth cookies.
> In the case of WebHDFS the shared secret used by NN and DNs could be used. In the case
of Oozie HA, the secret could be stored in Oozie HA control data in ZooKeeper.
> In addition, it is desirable for the secret to change periodically, this means that the
AuthenticationService should remember a previous secret for the max duration of hadoop-auth
cookie.
