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 The wiki page http://wiki.apache.org/hadoop/EclipseEnvironment has some out of date information,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