Josh Elser commented on HADOOP-10776:
-------------------------------------
[~vinodkv], was avoiding o.a.h.s.token.SecretManager (and only opening up
AbstractDelegationTokenSecretManager) intentional? A quick grep on one
downstream project where I wired up delegation support shows that I had used
SecretManager directly (which can probably be assumed that I copied it from
another project).
Although, if AbstractDelegationTokenSecretManager is Public, there are still
some abstract methods on SecretManager that I'd need to implement when
extending AbstractDelegationTokenSecretManager (which are still LimitedPrivate).

> Storm would like to be able to fetch delegation tokens and forward them on to
> running topologies so that they can access HDFS (STORM-346). But to do so we
> need to open up access to some of APIs.
> Most notably FileSystem.addDelegationTokens(), Token.renew,
> Credentials.getAllTokens, and UserGroupInformation but there may be others.
> At a minimum adding in storm to the list of allowed API users. But ideally
> making them public. Restricting access to such important functionality to
> just MR really makes secure HDFS inaccessible to anything except MR, or tools
> that reuse MR input formats.
