Would like to update development getting started pages on hadoop wiki but don't have permission
-----------------------------------------------------------------------------------------------

                 Key: HADOOP-7944
                 URL: https://issues.apache.org/jira/browse/HADOOP-7944
             Project: Hadoop Common
          Issue Type: Task
          Components: documentation
    Affects Versions: 0.23.0
         Environment: Ubuntu 10.04.2 LTS
            Reporter: Mark Pollack
            Priority: Minor


I've created an account on the wiki but can't edit pages.

The wiki page http://wiki.apache.org/hadoop/EclipseEnvironment has some out of date information,
for example 

mvn test -DskipTests
mvn eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true
cd ../; cd mapreduce; ant compile eclipse

should be

mvn install -DskipTests
mvn eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true


'install' is needed instead of test in order to get the build artifacts in the local M2 repo
for reference in the eclipse build path.  Also there isn't a 'mapreduce' directory anymore
and the mvn eclipse:eclipse command craetes the necessary .project files under the 0.23 'hadoop-mapreduce-project'
directory.

I'd also like to add a blurb about using eclipse with m2e/m2eclipse.  For a maven based project
many devs would just import the root pom.xmls.  With the new release of the m2e plug-in, this
doesn't work anymore as pretty much all targets are not supported by the new 'connector framework'
- yes, it is a giant mess.  This means falling back to m2eclipse or just doing the eclipse
generation as mention.

Adding a pointer to http://wiki.apache.org/hadoop/HowToContribute such that the requirements
to install java, maven, and protoc compilers would be helpful.  The information on getting
started from scratch seems a bit scattered and I'd like to help clean that up.

Please let me know how I can help to contribute in this area.
