Subject [jira] Commented: (HADOOP-7069) Replace forrest with supported framework
Date Wed, 05 Jan 2011 06:26:47 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7069?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12977643#action_12977643

Scott Carey commented on HADOOP-7069:

bq. The mavenization effort is a huge amount of work that would be great to get done, but
it's probably too big (x3 - thanks project split!)

Its nothing like 3x the work, if done right.  Most of the work would end up in a parent project
pom.xml(s) that all 3 projects would inherit from.   They could then be built together or

For Avro, the dropping of the JDK5 requirement is huge and we may not switch soon without
that as a motivating force.  But other tools, like Sphynx  (http://sphinx.pocoo.org/) are
interesting in part because they can have a custom look/feel easily and ... look good :) 
We also have to support build artifacts and documentation for many languages so the python
origins of something like Sphynx isn't a barrier to entry.

Maven provides a lot out of the box, but it is ugly and the site will look like a maven project
unless customized.  Its great for what it does by default trivially but is built for convention
and not customization.  Build a project with Maven and you get a site for free with zero effort
and some extras with little work at all.   But it is focused on build artifacts and a few
faq-like pages. Build a maven plugin and the docs it generates are beautiful right out of
the box -- coming from annotations /javadoc in your classes. Want to add a bunch of custom
documentation or document types?  significantly change look/feel? -- not so trivial.

> It's time to burn down the forrest.  Apache forrest, which is used to generate the documentation
for all three subprojects, has not had a release in several years (0.8, the version we use
was released April 18, 2007), and requires JDK5, which was EOL'ed in November 2009.  Since
it doesn't seem likely Forrest will be developed any more, and JDK5 is not shipped with recent
OSX versions, or included by default in most linux distros, we should look to find a new documentation
system and convert the current docs to it.
