Chris Nauroth commented on HDFS-9552:
-------------------------------------
The whitespace warning was triggered on a file not included in my patch. This
is because the site build copies hdfs-default.xml to src/site/resources. That
could be considered a build bug. It's bad form for the build to write into src.
I'll commit this.
> Document types of permission checks performed for HDFS operations.

> 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.
