Arpit Agarwal commented on HDFS-9552:
-------------------------------------
Nice work [~cnauroth], thanks for documenting this.
Should this be {{WRITE (target)}} instead of {{WRITE (source)}}?
{code}
concat | NO [2] | WRITE (source) | N/A | READ
(source), WRITE (destination) | N/A
{code}
The rest looks good to me.
> 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.
