1.首先在浏览器下载eclipse,网址如下
http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/neon/1a/eclipse-jee-neon-1a-linux-gtk-x86_64.tar.gz
2.解压eclipse安装包
首先将eclipse安装包复制到/opt下:
cp /home/hadoop/Downloads/eclipse-jee-neon-1a-linux-gtk-x86_64.tar.gz /opt/
接着解压:
tar -zxvf eclipse-jee-neon-1a-linux-gtk-x86_64.tar.gz
3.使用符号连接目录
ln -s /opt/eclipse/eclipse /usr/bin/eclipse
4.创建一个桌面启动器
vim /usr/share/applications/eclipse.desktop
添加如下代码:
[Desktop Entry]
Encoding=UTF-8
Name=Eclipse
Comment=Eclipse
Exec=/usr/bin/eclipse
Icon=/opt/eclipse/icon.xpm
Categories=Application;Development;Java;IDE
Version=1.0
Type=Application
Terminal=0
5.下载Hadoop-Eclipse插件,要注意hadoop版本的对应,我的hadoop版本是2.7.3
下载网址为:http://download.csdn.net/detail/tondayong1981/9668289
6.将插件放在解压后的eclipse的plugins目录下(在此处我的完整目录为/opt/eclipse/plugins)
7.重启eclipse,然后打开
Windows-Preferences
,在窗口左侧的Hadoop Map/Reduce选项设置hadoop的安装路径(我的hadoop安装路径为/home/hadoop/hadoop-2.7.3)
8.Eclipse上,打开
Windows-Perspective-Open Perspective-Other
,选择MapReduce,点击OK,然后在General处配置MapReduce的Location name(此处我填的是myhadoop)、Map/Reduce Master(此处我填的是Host:master,Port:9001)以及DFS Master(此处我填的是Port:9000)。
只要保证Map/Reduce Master和DFS Mastrer,Host和Port配置成与core-site.xml的设置一致即可。
9.上述配置完毕后会在eclipse左侧Project Explorer处有DFS Locations显示,可以看到我的hdfs的存储目录及其中的文件,如下图所示:
