Goal: Compile the Eclipse plugin for Apache Hadoop2.2.0 in the win7x64 environmentEnvironment:Win7x64 Family Normal edition Eclipse-jee-kepler-sr1-win32-x86_64.zipapache Ant (TM) version 1.8.4 compiled on 2012java version " 1.7.0_45 "Reference article: http://kangfoo.u.qiniudn.com/article/2013/12/build-hadoop2x-eclipse-plugin/plugin source code download: https:// Github.com/winghc/hadoop2x-eclipse-plugin Prerequisites: Ant, jdk, Eclipse, Apache Hadoop 2.2.0 installation package are ready plug-in source package has been downloaded on the virtual machine has been deployedApache Hadoop 2.2.0 Environment
Step 1:will beApache Hadoop 2.2.0 Install package Copy to random Windows folder, I use the folder isD:\Development_ProgramFiles_2014\hadoop-2.2.0 Remember: The entire path does not appear with spaces. Otherwise, the ant compilation process will be faulted.
Step 2(This step should be able to omit): Copy the directory hadooproot/etc/hadoop/the storage configuration file for the Hadoop cluster toD:\Development_ProgramFiles_2014\hadoop-2.2.0\etc under
Step 3:Execute cmd,Enter the plugin source code root folder. ExecutionCD Src/contrib/eclipse-plugin
Step 4: RunAnt jar-dversion=2.2.0
-declipse.home = D:\Development_ProgramFiles_2014\eclipse2014
-dhadoop.home=D:\Development_ProgramFiles_2014\hadoop-2.2.0
Note: The command needs to specify the target Eclipse installation folder, the Hadoop installation folder, to compile the plug-in.
Remember: There are no spaces in the full path of the two folders.
Step 5: Then is the long wait, the main slow target:ivy-download. Ivy-resolve-common these two steps.the last generated plug-inHadoop2x-eclipse-plugin-master\build\contrib\eclipse-plugin\hadoop-eclipse-plugin-2.2.0.jar
Step 6:WillHadoop-eclipse-plugin-2.2.0.jar Copy to Eclipse's plugins folder, launch Eclipse
Step 7:window--"Preferences Configure the Hadoop root folder:
Note: Configure this path, however, in order to run the Mr Procedure. Eclipse can find the corresponding jar package.
Step 8:Open the MapReduce view:
Configure location:
watermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqvznvsb25nzmjp/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/ Dissolve/70/gravity/southeast "style=" border:none; max-width:100% ">
Note: The MR master and DFS master configurations must be consistent with the configuration files such as Mapred-site.xml and Core-site.xml.
Step 9: Open Project Explorer. To view the HDFs file system:
Step Ten: create a new MapReduce project
To create a MapReduce program:

Execute the MR Program. Tip You cannot connect to a cluster, please see the article:
