Rick Kazman commented on HDFS-1961:
-----------------------------------
I have updated the HDFS 0.21 architectural documentation at
http://kazman.shidler.hawaii.edu/ArchDoc.html to include a module view of the
architecture. This representation depicts the HDFS codebase a 10 interconnected
modules. It also highlights some unhealthy dependencies between modules that
can limit system evolution.
As always, comments appreciated!

> This material provides an overview of the HDFS architecture and is intended
> for contributors. The goal of this document is to provide a guide to the
> overall structure of the HDFS code so that contributors can more effectively
> understand how changes that they are considering can be made, and the
> consequences of those changes. The assumption is that the reader has a basic
> understanding of HDFS, its purpose, and how it fits into the Hadoop project
> suite.
