如何編譯hadoop1.x的eclipse插件

小編給大家分享一下如何編譯hadoop1.x的eclipse插件，希望大家閱讀完這篇文章之后都有所收獲，下面讓我們一起去探討吧！

注意：以下操作基于Hadoop-1.2.1，Eclipse Luna，Win7 64位

1、將hadoop eclipse插件的工程導入Eclipse。插件源碼目錄如下：

D:\Lab\lib\hadoop\hadoop-1.2.1\src\contrib\eclipse-plugin

2、配置工程依賴

3、準備ant的配置文件

D:\Lab\lib\hadoop\hadoop-1.2.1\src\contrib\build-contrib.xml

將以上build-contrib.xml拷貝到項目目錄中，并修改文件內容。具體如下：

  <property name="name" value="${ant.project.name}"/>
  <property name="root" value="${basedir}"/>
  <property name="hadoop.root" location="D:/Lab/lib/hadoop/hadoop-1.2.1"/>
  <property name="eclipse.home" location="D:/Program Files/Eclipse/eclipse-jee-luna-R-win32-x86_64"/>
  <property name="version" value="1.2.1"/>
  <property name="build.contrib.dir" location="${root}/build/contrib"/>
  <property name="build.dir" location="${root}/build/contrib/${name}"/>

4、修改build.xml

<!-- 1.修改 build-contrib.xml的位置，去掉"../" -->
<import file="build-contrib.xml" />

<!-- 2.添加如下，否則提示"軟件包 org.apache.hadoop.fs 不存在" -->
<path id="hadoop-jars">
    <fileset dir="${hadoop.root}/">
        <include name="hadoop-*.jar" />
    </fileset>
</path>

<!-- Override classpath to include Eclipse SDK jars -->
<path id="classpath">
    <pathelement location="${build.classes}" />
    <pathelement location="${hadoop.root}/build/classes" />
    <path refid="eclipse-sdk-jars" />
    <path refid="hadoop-jars" /><!--本行為添加內容-->
</path>

<!-- 3.修改并添加jar包,有些包已經有了,只添沒有的   -->
<!-- Override jar target to specify manifest -->
<target name="jar" depends="compile" unless="skip.contrib">
    <mkdir dir="${build.dir}/lib" />
    <copy file="${hadoop.root}/hadoop-core-${version}.jar" tofile="${build.dir}/lib/hadoop-core.jar" verbose="true" />
    <copy file="${hadoop.root}/lib/commons-cli-1.2.jar" todir="${build.dir}/lib" verbose="true" />
    <copy file="${hadoop.root}/lib/commons-lang-2.4.jar" todir="${build.dir}/lib" verbose="true" />
    <copy file="${hadoop.root}/lib/commons-configuration-1.6.jar" todir="${build.dir}/lib" verbose="true" />
    <copy file="${hadoop.root}/lib/commons-httpclient-3.0.1.jar" todir="${build.dir}/lib" verbose="true" />
    <copy file="${hadoop.root}/lib/jackson-mapper-asl-1.8.8.jar" todir="${build.dir}/lib" verbose="true" />
    <copy file="${hadoop.root}/lib/jackson-core-asl-1.8.8.jar" todir="${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>

5、修改MENIFEST.MF，在Bundule-ClassPath中增加一些依賴的jar。

Bundle-ClassPath: classes/,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/hadoop-core-1.2.1.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-cli-1.2.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-configuration-1.6.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-httpclient-3.0.1.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-lang-2.4.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/jackson-core-asl-1.8.8.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/jackson-mapper-asl-1.8.8.jar

5、增加Ant Builder。

6、編譯

在Project菜單中Build Project

7、運行結果
