如何编译hadoop1.x的eclipse插件

小编给大家分享一下如何编译hadoop1.x的eclipse插件，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

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

1、将hadoop eclipse插件的工程导入Eclipse。插件源码目录如下：

D:Lablibhadoophadoop-1.2.1srccontribeclipse-plugin

2、配置工程依赖

3、准备ant的配置文件

D:Lablibhadoophadoop-1.2.1srccontribbuild-contrib.xml

将以上build-contrib.xml拷贝到项目目录中，并修改文件内容。具体如下：

  <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，否则提示"软件包 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="${hadoop.root}/build/classes" />      <path refid="eclipse-sdk-jars" />      <path refid="hadoop-jars" /><!--本行为添加内容-->  </path>    <!-- 3.修改并添加jar包,有些包已经有了,只添没有的   -->  <!-- Override jar target to specify manifest -->  <target name="jar" depends="compile" unless="skip.contrib">      <mkdir dir="${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中增加一些依赖的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、编译

在Project菜单中Build Project

7、运行结果
