> We've recently had a spate of questions on the users list regarding features such as
rack-awareness, the trash can etc. which are not clearly documented from a user/admins perspective.
There is some Javadoc present but most of the "documentation" exists either in JIRA or in
the default config files themselves.
> We should generate top down configuration and use guides for map/reduce and HDFS. These
should probably be in forest and accessible from the project website (Javadoc isn't always
approachable to our non-programmer audience). Committers should look for user documentation
before accepting patches.
