Ubuntu 搭建Hadoop源码阅读环境

Ant安装：

下载ant:http://ant.apache.org/bindownload.cgi

解压Ant:

tar -xvzf apache-ant-1.9.2-bin.tar.gz

移动重命名：

  mv apache-ant-1.9.2/ ~/opt/
  mv apache-ant-1.9.2/ ant

配置环境变量，添加ANT_HOME，和$ANT_HOME/bin：

sudo vim /etc/profile

  .......................
  export ANT_HOME=/opt/ant
  export PATH=$PATH:$ANT_HOME/bin
 .......................

source /etc/profile

测试是否生效：

 ant -version
Apache Ant(TM) version 1.9.2 compiled on July 8 2013

Hadoop Eclipse 插件安装：

Hadoop的eclipse插件需要自行安装编译，也很简单，用ant进行编译打包

cd /opt/hadoop-1.2.1/src/contrib/eclipse-plugin

此处贴出build.xml全部和META-INFO改动的：

build.xml
