> We need a plugin API to translate long principal names (e.g. 
> john....@example.com) to local OS user names (e.g. user123456) arbitrarily.
> For some organizations the name translation is straightforward (e.g. 
> john....@example.com 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.
