Use Ant to compile the Hadoop eclipse plug-in

I have successfully generated a plug-in using this method.

Download hadoop's release,

Download ant

Decompress ant to the hard disk, such as D: \ ant.

Set Environment Variables

Ant_home = D: \ ant

Add % ant_home % \ bin to path.

Decompress hadoop's release.

Enter % hadoop_home % \ SRC \ contrib \

Edit build-contrib.xml

Join

<Property name = "version" value = "1.0.3"/>

<Property name = "Eclipse. Home" location = "D:/soft/eclipse-jee-indigo-SR1-win32/Eclipse"/>

Copy the jar package under % hadoop_home % To the Plugins directory of the eclipse directory, such as hadoop-core-*. jar.

Enter % hadoop_home % \ SRC \ contrib \ eclipse-plugin

Edit build. xml

In

<Path id = "eclipse-SDK-jars">

<Fileset dir = "$ {eclipse. Home}/plugins/">

</Fileset>

</Path>

Join

<Include name = "hadoop *. jar"/>

In the compile module

Deprecation = "$ {javac. deprecation}

Remove.

Open CMD and use ant in % Hadoop_HOME % \ src \ contrib \ eclipse-plugin

Then compile.

BUILD SUCCESSFUL 
  
  
Total time: 2 seconds 
 
 

Note: errors may be reported during compilation, mainly due to the copy problem during jar, copy the commons-cli-1.2.jar and to % HADOOP_HOME % \ build \ ivy \ lib \ Hadoop \ common \, copy the hadoop-core-1.0.3.jar to % HADOOP_HOME % \ build.

These directories may not exist. Create one by yourself!

After compilation is successful, the hadoop-eclipse-plugin-1.0.3.jar is generated under % Hadoop_Home % \ build \ contrib \ eclipse-plugin. Copy it to the plugins directory in the eclipse directory. Re-open eclipse

Select window-open perspective-other and you will see

Select Map/Reduce

Select window-show view-other

Select Map/Reduce Locaions

The hadoop plug-in of eclipse is compiled successfully.
