This article mainly explains how to compile and install the detailed process of Hadoop2.xeclipseplugin plug-in: Environment Parameter compilation process installation and configuration [1], Environment Parameter EclipseJunoServiceRelease2Hadoop2.2.0Java1.6.0 _ 65MacOXS10. 9.2 [2]. Currently, the source code of the Hadoop2.x plug-in is hosted on github,

This article describes how to compile, install, and configure the Hadoop2.x eclipse plugin: install and configure environment parameters during compilation [1]. The environment parameters are Eclipse Juno Service Release 2 Hadoop2.2.0 Java 1.6.0 _ 65 Mac OXS 10.9.2 [2]. Currently, the source code of the Hadoop2.x plug-in is hosted on github.,

This article describes how to compile, install, and configure the Hadoop2.x eclipse plugin:

• Environment Parameters
• Compilation process
• Install configurations

[1]. Environment Parameters

• Eclipse Juno Service Release 2
• Hadoop2.2.0
• Java 1.6.0 _ 65
• Mac OXS 10.9.2

[2] compilation processCurrently, the source code of the Hadoop2.x plug-in is hosted on github. The first step is to download the source code.

git clone https://github.com/winghc/hadoop2x-eclipse-plugin.git

Compile source code:

$cd src/contrib/eclipse-plugin$ant jar -Dversion=2.2.0 -Declipse.home=/Applications/eclipse -Dhadoop.home=/usr/local/share/hadoop

However, the first compilation failed on my machine, similar to the following error message:

............[javac] Compiling 45 source files to /Users/micmiu/no_sync/opensource_code/hadoop/hadoop2x-eclipse-plugin/build/contrib/eclipse-plugin/classes    [javac] /Users/micmiu/no_sync/opensource_code/hadoop/hadoop2x-eclipse-plugin/src/contrib/eclipse-plugin/src/java/org/apache/hadoop/eclipse/MapReduceNature.java:35: package org.eclipse.jdt.core does not exist    [javac] import org.eclipse.jdt.core.IClasspathEntry;    [javac]                            ^    [javac] /Users/micmiu/no_sync/opensource_code/hadoop/hadoop2x-eclipse-plugin/src/contrib/eclipse-plugin/src/java/org/apache/hadoop/eclipse/MapReduceNature.java:36: package org.eclipse.jdt.core does not exist    [javac] import org.eclipse.jdt.core.IJavaProject;    [javac]                            ^..............

It is estimated that my eclipse does not org.eclipse.jdt.core*Related lib package, unable to find the class caused, then go to my local directory? /Applications/eclipse/plugins/The following shows that there is indeed no similar lib package, which proves the previous judgment. I had to find org.eclipse.jdt.core_3.7.3.v20120119-1537.jar? Copy to the plug-in source code directory? src/contrib/eclipse-plugin/libAnd must be modified at the same time? src/contrib/eclipse-plugin/build.xmlFile, add the following two modifications:

  
   
   
     
        
       
     
 ......
   
     
      
      
      
      
      
    
 ......

Then execute the compilation command to see? Build successful indicates that the compilation is SUCCESSFUL:

After compilation, you can? Build/contrib/eclipse-plugin/hadoop-eclipse-plugin-2.2.0.jar find the generated jar package. : Http://yun.baidu.com/s/1o6K457c#dir/path=%2Fsourcecode%2Fbuilder [3] installation and configuration1. Copy the generated hadoop-eclipse-plugin-2.2.0.jar to the eclipse/plugins path, restart eclipse. 2. click in the eclipse menu? Windows →? Show view →? Other... In the Show View dialog box, enter "map" in the search box, find the "Map/Reduce Locations" option, and click "OK: 3. A "Map/Reduce Locations" Tab page appears on the console: 4. Click the icon on the "Map/Reduce Locations" Tab page? Or right-click the blank area and select "New Hadoop location ...", The dialog box "New hadoop location…" is displayed ...", The configuration is as follows:

• Location name: a random name, for example, hadoop2.2.0
• Map/Reduce (V2) Master: Based onhdfs-site.xmlSet the value of dfs. datanode. ipc. address in
• DFS Master: the IP address and port of the Name Node.core-site.xmlConfigure fs. defaultFS value in

After successful configuration, you can see the following information: 5. Open the "preferences" dialog box, search for "hadoop", find the "Hadoop Map/Reduce" item, and click "Browse ..." Configure the hadoop path, for example, my path is /usr/local/share/hadoop-2.2.0------? EOF? @ Michael Sun? ------
