hadoop2x-eclipse-plugin在hadoop 2.7.5下编译和在hadoop完全分布式下的使用

1. 下载plugin source code
    git clone git://github.com/winghc/hadoop2x-eclipse-plugin

2. 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
    2.1 修改build.xml
   

1. 在第81行 找到 , 在第82行 找到 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
   , 添加下面3行 )
   <copy file="${hadoop.home}/share/hadoop/common/lib/htrace-core-${htrace.version}-incubating.jar"  todir="${build.dir}/lib" verbose="true"/> 
   <copy file="${hadoop.home}/share/hadoop/common/lib/servlet-api-${servlet-api.version}.jar"  todir="${build.dir}/lib" verbose="true"/> 
   <copy file="${hadoop.home}/share/hadoop/common/lib/commons-io-${commons-io.version}.jar"  todir="${build.dir}/lib" verbose="true"/>
   然后找到标签 lib/servlet-api-${servlet-api.version}.jar,
   lib/commons-io-${commons-io.version}.jar,
   lib/htrace-core-${htrace.version}-incubating.jar"/>

slf4j-log4j12.version=1.7.10
#xerces.version=1.4.4    modify
xerces.version=2.9.1

3. 编译plugin
    3.1

1. cd \src\contrib\eclipse-plugin\
   Run: ant jar -Dversion=2.7.5 -Dhadoop.version=2.7.5 -Declipse.home=C:\IES4.6.1\sdk -Dhadoop.home=C:\software\hadoop-2.7.5 -debug
2. If any error occurs, modify the C:\IES4.6.1\workspace_yanxluo1\hadoop2x-eclipse-plugin\ivy\libraries.properties to update the library version. The libraries is located in \share\hadoop\common\lib.
3. copy the hadoop-eclipse-plugin-2.7.5.jar from C:\IES4.6.1\workspace_yanxluo1\hadoop2x-eclipse-plugin\build\contrib\eclipse-plugin to your eclipse_home/plugins

4. Download the hadoop dll files from http://download.csdn.net/download/loliaryx/10217212

5. Copy the dll files to the %HADOOP_HOME\bin folder

6. Define the env HADOOP_HOME in the system variable, and add %HADOOP_HOME% to the PATH env

7. Start eClipse with "eclipse -clean”

8. Open Map/Reduce perspective

9. New a Map/Reduce location, the port of the Map/Reduce(V2) is to the yarn port.

10 . Edit the "Advanced parameters"
   dfs.namenode.edits.dir   dfs.datanode.data.dir 修改为实际的地址
