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