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The wiki page http://wiki.apache.org/hadoop/EclipseEnvironment has some out of
date information, for example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