hadoop 2.7.3 (hadoop2.x)使用ant制作eclipse插件hadoop-eclipse-plugin-2.7.3.jar
为了做mapreduce开发,要使用eclipse,并且需要对应的Hadoop插件hadoop-eclipse-plugin-2.7.3.jar,首先说明一下,在hadoop1.x之前官方hadoop安装包中都自带有eclipse的插件,而如今随着程序员的开发工具eclipse版本的增多和差异,hadoop插件也必须要和开发工具匹配,hadoop的插件包也不可能全部兼容.为了简化,如今的hadoop安装包内不会含有eclipse的插件.需要各自根据自己的eclipse自行编译.
1. 环境准备
使用ant制作自己的eclipse插件,介绍一下我的环境和工具 ( 安装路径根据自己 )
系统: 64bit Ubuntu 14.04,(系统不重要Win也可以,方法都一样)
JDK 版本: jdk-7u80-linux-x64.tar.gz 安装路径： /usr/lib/jvm
eclipse 版本: ide工具eclipse-jee-mars-2-linux-gtk-x86_64.tar.gz 安装路径： /home/hadoop/
hadoop 版本: hadoop-2.7.3.tar.gz 安装路径：/usr/local
ant(这个也随意,二进制安装或者apt-get安装都可以,配置好环境变量) , 我的 ant 版本是1.9.3 , 有的是 1.9.7
export ANT_HOME=/usr/local/apache-ant-1.9.3
export PATH=$PATH:$ANT_HOME/bin
如果提示找不到ant的launcher.ja包,添加环境变量
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/toos.jar:$ANT_HOME/lib/ant-launcher.jar
$ ant -version
Apache Ant(TM) version 1.9.3 compiled on April 8 2014
我使用的是GitHub 上的 hadoop2x-eclipse-plugin （https://github.com/winghc/hadoop2x-eclipse-plugin）提供的 hadoop2x-eclipse-plugin-master.zip ( 这是最新的 ,它对应 hadoop2x-eclipse-plugin-2.6.0.zip ),
以zip格式下载,然后解压到一个合适的路径下.注意路径的权限和目录所有者是当前用户下的.
三个编译工具和资源的路径如下:
eclipse : /home/hadoop/eclipse
hadoop : /usr/local/hadoop-2.7.3
hadoop2x-eclipse-plugin-master : /home/hadoop/hadoop2x-eclipse-plugin-master
2 制作 hadoop-eclipse-plugin-2.7.3.jar
但是我的hadoop版本是2.7.3,所以需要另外制作插件，好在这篇Github文章提供了怎么build插件的方法。
解压下载过来的hadoop2x-eclipse-plugin,进入其中目录hadoop2x-eclipse-plugin-master/src/contrib/eclipse-plugin/执行操作, Github文章提供了怎么build插件的方法如下所示:
eclipse plugin for hadoop 2.x.x
How to build
[hdpusr@demo hadoop2x-eclipse-plugin]$ cd src/contrib/eclipse-plugin
# Assume hadoop installation directory is /usr/share/hadoop
[hdpusr@apclt eclipse-plugin]$ ant jar -Dversion=2.4.1 -Dhadoop.version=2.4.1 -Declipse.home=/opt/eclipse -Dhadoop.home=/usr/share/hadoop
final jar will be generated at directory
${hadoop2x-eclipse-plugin}/build/contrib/eclipse-plugin/hadoop-eclipse-plugin-2.4.1.jar
2.1 修改相关文件, 主要有两个,一个是 hadoop2x-eclipse-plugin-master/src/contrib/eclipse-plugin/build.xml , 第二个是 hadoop2x-eclipse-plugin-master/ivy/libraries.properties
但是此时我需要的是 hadoop 2.7.3的 eclilpse 插件,而 github 下载过来的 hadoop2x-eclipse-plugin 配置是 hadoop2.6 的编译环境,所以执行 ant 之前需要需要修改 ant 的 build.xml 配置文件以及相关文件
第一个文件: hadoop2x-eclipse-plugin-master/src/contrib/eclipse-plugin/build.xml , 如下所示:

在第81行 找到 <!-- Override jar target to specify manifest --> , 在第82行 找到 <target name="jar" depends="compile" unless="skip.contrib">标签,添加和修改copy子标签标签一下内容, 也就是127行下面, 如下 ( 删除第127行

然后找到标签<attribute name="Bundle-ClassPath" ( 在修改之前的配置文件 build.xml 第133行 )在齐总的value的列表中对应的添加和修改lib,如下 ( 删除第154行 lib/htrace-core-${htrace.version}.jar, 添加下面3行 )

但是只是添加和修改这些lib是不行的,hadoop2.6到hadoop2.7中share/hadoop/common/lib/下的jar版本都是有很多不同的,因此还需要修改相应的jar版本. 这个耗费了我半天的时间啊.一个个的对号修改.
注意这个版本的环境配置文件在hadoop2x-eclipse-plugin-master跟目录的ivy目录下,也就 hadoop2x-eclipse-plugin-master/ivy/libraries.properties 中, ( 将libraries.properties 的 各个选项与 hadoop 各个相应选项( 在 share/hadoop/的几个文件夹下 )的版本号相对应 , )

修改完成后,大功告成,开始ant
2.2 开始 ant
进入src/contrib/eclipse-plugin/执行ant命令,如下 ( 权限不够的话,可以切换到 root 权限, 命令 su root )
$ cd /home/hadoop/hadoop2x-eclipse-plugin-master/src/contrib/eclipse-plugin/
$ su root
$ ant jar -Dhadoop.version=2.7.3 -Declipse.home=/home/hadoop/eclipse -Dhadoop.home=/usr/local/hadoop-2.7.3
这个过程第一次会慢点,后来就会很快.
当最终显示如下,就表示ant制作成功:

然后你可以切换到 /home/hadoop/hadoop2x-eclipse-plugin-master/build/contrib/eclipse-plugin/, 下面有我们制作好的插件 hadoop-eclipse-plugin-2.7.3.jar.
3 将自己制作的插件放入到eclipse目录的plugins下, 并配置 Hadoop-Eclipse-Plugin ( 这里就要求本机上搭建了伪分布式或全分布式 )
可以参考 使用Eclipse编译运行MapReduce程序 Hadoop2.6.0_Ubuntu/CentOS
然后将自己制作的插件放入到eclipse目录的plugins下
然后重启eclipse或者shell命令行刷新eclipse如下,同时也可以在shell中显示eclipse的运行过程,以及出错后及时发现原因
$ cp /home/hadoop/hadoop2x-eclipse-plugin-master/build/contrib/eclipse-plugin/hadoop-eclipse-plugin-2.7.2.jar /home/hadoop/eclipse/plugins/
$ /home/hadoop/eclipse/eclipse -clean
