Allen Wittenauer commented on HADOOP-11683:
-------------------------------------------
Just a pre-emptive comment: :)
Be aware that HadoopKerberosName is now exposed to users in trunk. We should
make sure that the solution here also works there.

> We need a plugin API to translate long principal names (e.g.
> [email protected]) to local OS user names (e.g. user123456) arbitrarily.
> For some organizations the name translation is straightforward (e.g.
> [email protected] to john_doe), and the hadoop.security.auth_to_local
> configurable mapping is sufficient to resolve this (see HADOOP-6526).
> However, in some other cases the name translation is arbitrary and cannot be
> generalized by a set of translation rules easily.
