------------------------------------------------
Summary: Improve instructions for Eclipse with m2e plugin in
http://wiki.apache.org/hadoop/EclipseEnvironment
Key: HADOOP-9771
URL: https://issues.apache.org/jira/browse/HADOOP-9771
Project: Hadoop Common
Issue Type: Improvement
Components: documentation
Affects Versions: 3.0.0, 2.0.5-alpha
Environment: Cent OS 6.4
Reporter: German Florez-Larrahondo
Priority: Minor
The instructions for using Eclipse with Hadoop 2.0x or trunk seem a bit out of
date. I recently setup Eclipse with the m2e plugin without major issues (in
contrast, the wiki calls it a 'giant mess').
I think we should have instructions for both the m2e plugin and with more
static mvn eclipse:eclipse option as in the current wiki.
Below I add a raw log of the steps I took. If I get granted write access to
this wiki page I could do a nice write-up of this if the team agrees with the
updates (my wiki name is GermanFlorezLarrahondo)

Raw log of activities to compile Hadoop in Eclipse using m2e pluging (As of
July 25 2013):
-Using trunk (http://svn.apache.org/repos/asf/hadoop/common/trunk), Last
Changed Date: 2013-07-24 10:00:50 -0400 (Wed, 24 Jul 2013)
-first built by hand via CLI using mvn -o -X $ANT_OPTS clean package
-Pdist,native,docs,src -DskipTests -Dtar
-Follow most of the instructions in here
http://blog.cloudera.com/blog/2013/05/how-to-configure-eclipse-for-hadoop-contributions/
-In particular, for a clean build the proper protocol buffers and avro
autogenerated Java files must be linked to some of the Hadoop projects (via
buid path/link source, adding patter **/*.java).
