Linux under Hadoop Eclipse plugin compile install __linux

My Hadoop is 1.2.1 version, there are some compiled on the internet Hadoop plug-ins, but still do-it-yourself, ample clothing, later version of the update can compile their own plug-ins, and this will ensure that the installation in eclipse will not have too many problems.

Mainly refer to this article http://www.cnblogs.com/kinuxroot/archive/2013/05/06/linux_hadoop_eclipse_plugin.html

For easy viewing, or paste the information. Statement: I follow the previous explanation part of a little bit of code to add the time did not succeed, the use of the overall file behind, a slight modification after the success, it is really indiscriminate to add is not, after all, the version is not the same, in some places or different.

1. To join Eclipse settings and Hadoop version settings, my eclipse is installed under/home/kinuxroot/apps/eclipse, so we want to change it to:

<property name= "Eclipse.home" location= "/home/kinuxroot/apps/eclipse"/> <property
"version" value= "1.1.2"/>

This step, the path in the location please change according to their actual path.

2. We need to refer to some of the packages of Hadoop, but the default classpath do not have these packages (we did not compile from scratch). So you need to modify the Classpath
Positioning <path id= "Classpath", add:

<fileset dir= "${hadoop.root}" >
    <include name= "**/*.jar"/>
</fileset>

3. Some legacy functions are used in the code, so we need to modify the deprecation settings.
Open the src/contrib/build-contrib.xml below the Hadoop root path to locate

<property name= "javac.deprecation" value= "Off"/>

And then modify it into

<property name= "Javac.deprecation" value= "on"/>

4. Modify the Includeantruntime settings. Locate compile target, modify the Javac settings, and add an option
Includeantruntime= "On"
Which is to modify the Javac into

<javac
     encoding= "${build.encoding}"
     srcdir= "${src.dir}"
     includes= "
     **/*.java" destdir= "${" build.classes} "
     debug=" ${javac.debug} "
     deprecation= ${javac.deprecation}"
     includeantruntime= "on" >
     <classpath refid= "classpath"/>
</javac>

5.jar needed some jar files for Hadoop, but we didn't compile it, so we need to modify the jar target.

In addition, there are a few jars we need to use, and Build.xml does not contain automatically, if not included, Eclipse connect Hadoop will appear failure to login error, in fact, can not find the class
Found it

<copy file= "${hadoop.root}/build/hadoop-core-${version}.jar" tofile= "${build.dir}/lib/hadoop-core.jar" verbose = ' true '/>
<copy file= ' ${hadoop.root}/build/ivy/lib/hadoop/common/commons-cli-${commons-cli.version}. Jar "  todir=" ${build.dir}/lib "verbose= true"/>

We modify into

<copy file= ' ${hadoop.root}/hadoop-core-${version}.jar ' tofile= ' ${build.dir}/ Lib/hadoop-core.jar "verbose=" true "/> <copy file=" ${hadoop.root}/lib/commons-cli-${commons-cli.version}.jar "Tofile=" ${build.dir}/lib/commons-cli.jar "verbose=" true "/> <copy file=" ${hadoop.root}/lib/ Commons-configuration-1.6.jar "tofile=" ${build.dir}/lib/commons-configuration.jar "verbose=" true "/> <copy File= "${hadoop.root}/lib/commons-httpclient-3.0.1.jar" tofile= "${build.dir}/lib/commons-httpclient.jar" verbose= "True"/> <copy file= "${hadoop.root}/lib/commons-lang-2.4.jar" tofile= "${build.dir}/lib/commons-lang.jar" Verbose= "true"/> <copy file= ${hadoop.root}/lib/jackson-core-asl-1.8.8.jar "tofile=" ${build.dir}/lib/ Jackson-core-asl.jar "verbose=" true "/> <copy file=" ${hadoop.root}/lib/jackson-mapper-asl-1.8.8.jar "tofile=" ${build.dir}/lib/jackson-mapper-asl.jar "verbose= true"/> 

6. However, our jar files are not automatically deployed to eclipse, you can copy them manually, but we want ant to help us deploy them automatically.
We create a new target to deploy:

<target name= "Deploy" depends= "jar" unless= "Skip.contrib" > <copy file= "${build.dir}/hadoop-${name}-${"
Version}.jar "  todir=" ${eclipse.home}/plugins "verbose=" true "/>
</target>

Then modify project's default target, which is to modify project to:

<project default= "Deploy" name= "Eclipse-plugin" >

7. The next step is to modify the src/contrib/eclipse-plugin/meta-info/manifest in the Hadoop root directory. MF, modify the classpath of this jar.

Find this line of Bundle-classpath for this file, and then, modify it into

bundle-classpath:classes/,lib/commons-cli.jar,lib/commons-httpclient.jar,lib/hadoop-core.jar,lib/ Jackson-mapper-asl.jar,lib/commons-configuration.jar,lib/commons-lang.jar,lib/jackson-core-asl.jar

8. Execute ant, the code will be compiled, the plug-in will be automatically installed into Eclipse's plugins directory, open eclipse will be available (if Ant is not installed,
Go to Apache and wait and see to download the binary version of Ant. In addition, the compilation will automatically download the required package, so please ensure the network unobstructed.

Finally, I put my build.xml on the following, you can refer to:
