Compiling the Eclipse Hadoop plugin

Operating system: Ubuntu

Hadoop version: 1.0.1

Eclipse Version: Eclipse HELIOS-SR2

The eclipse plug-in generated directly from the Hadoop 1.0.1 mask plugin is not available because some jar packages are missing, so you need to manually modify the Build.xml files and meta-inf/in the Src/contrib/eclipse-plugin directory MANIFEST. MF file.

1. Modify the Build.xml file

It's not a modification.

<target name= "Jar" depends= "compile" unless= "Skip.contrib" > <mkdir dir= "${build.dir}/lib"/> <copy fil E= "${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 "/> jarfile=" ${build.dir}/hadoop-${name}-${version}.jar "manifest=" ${root}/META- Inf/manifest. MF "> <fileset dir=" ${build.dir} "includes=" classes/lib/"/> <fileset dir=" ${root} "includes=" Resourc Es/plugin.xml "/> </jar> </target>

Modify it on this basis and modify it to

<target name= "Jar"  depends= "compile"  unless= "Skip.contrib" >    < Mkdir dir= "${build.dir}/lib"/>    <copy file= "${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=" ${build.dir}/lib " verbose=" true "/>       <copy file= "${hadoop.root}/build/ivy/lib/hadoop/common/commons-configuration-1.6.jar"   todir= "${build.dir}/lib"  verbose= "true"/>      <copy  file= "${hadoop.root}/build/ivy/lib/hadoop/common/commons-lang-2.4.jar"   todir= "${build.dir}/ Lib " verbose=" true "/>      <copy file=" ${hadoop.root}/build/ivy/ Lib/hadoop/common/jackson-core-asl-1.8.8.jar "  todir= "${build.dir}/lib"  verbose= "true"/>      <copy file= "${hadoop.root}/build/ivy/lib/hadoop/common/jackson-mapper-asl-1.8.8.jar"   todir= "${build.dir}/lib"  verbose= "true"/>      <copy file= "${hadoop.root}/build/ivy/lib/ Hadoop/common/commons-httpclient-3.0.1.jar "  todir=" ${build.dir}/lib " verbose=" true "/>     <jar      jarfile= "${build.dir}/hadoop-${name}-${version}. Jar "      manifest=" ${root}/meta-inf/manifest. MF ">      <fileset dir=" ${build.dir} " includes=" classes/  lib/"/>      <fileset dir=" ${root} " includes=" resources/  Plugin.xml "/>    </jar>  </target>

2. Modify the Meta-inf/manifest. MF File

It's not a modification.

Bundle-classpath:classes/,lib/hadoop-core.jar

Modify it on this basis and modify it to

bundle-classpath:classes/,lib/hadoop-core.jar,lib/commons-cli-1.2.jar,lib/commons-configuration-1.6.jar,lib/ commons-lang-2.4.jar,lib/jackson-core-asl-1.8.8.jar,lib/jackson-mapper-asl-1.8.8.jar,lib/ Commons-httpclient-3.0.1.jar

Note To add all the jar packages defined in the Build.xml, I was the first to write less lib/commons-cli-1.2.jar, resulting in the use of or have been reported error:failure to login error, tossing for a long time (by the Hadoop Technology Insider "this book is misleading."

3. Compile the Build plugin jar package

command line into the Src/contrib/eclipse-plugin directory under the Hadoop installation directory, enter the following command:

Ant-declipse.home=/home/jason/eclipse-dversion=1.0.2-snapshot

Where eclipse.home is used to specify the path to eclipse, version is the release number of Hadoop.

Finally, you will see the generated jar package in the Build/contrib/eclipse-plugin directory under the Hadoop installation directory, and copy it to the Eclipse's plugin directory.
