Building Hadoop Source Jars

Script to build yourself the source jars for hadoop core:

• Download a hadoop release from http://www.apache.org/dyn/closer.cgi/hadoop/common/
• Unpack the tar.gz to a folder (in my case /opt/hadoop/)
• Copy the script below into a file names mk-source.sh (Amend the VERSION and HADOOP_SRC variables for your environment)
• Optionally install the sources into your local maven repository
  

  mvn install:install-file \
      -Dfile=/opt/hadoop/hadoop-0.20.2/src/hadoop-core-0.20.2-sources.jar \
      -DgroupId=org.apache.hadoop \
      -DartifactId=hadoop-core \
      -Dversion=0.20.2 \
      -Dpackaging=java-sources \
      -DgeneratePom=false
