> The HDFS permissions guide discusses our use of a POSIX-like model with read,
> write and execute permissions associated with users, groups and the catch-all
> other class. However, there is no documentation that describes exactly what
> permission checks are performed by user-facing HDFS operations. This is a
> frequent source of questions, so it would be good to document this.
