Tom White commented on HADOOP-6994:
-----------------------------------

The new methods on AbstractFileSystem are public, yet Token and AbstractDelegationTokenIdentifier are LimitedPrivate, which seems inconsistent.

> APIs to get delegation tokens is required in AbstractFileSystem. AbstractFileSystems are accessed via file context therefore an API to get list of AbstractFileSystems accessed in a path is also needed. 
> A path may refer to several file systems and delegation tokens could be needed for many of them for a client to be able to successfully access the path.
