配置ant

tar -zxvf apache-ant-1.9.2-bin.tar.gz

export ANT_HOME=/home/hadoop/apache-ant-1.9.2

export PATH=${JAVA_HOME}/bin:${HADOOP_HOME}/bin:${PIG_HOME}/bin:${ANT_HOME}/bin:$PATH

編譯生成插件包

1、解壓hadoop-1.1.2.tar.gz。如：/home/hadoop/hadoop-1.1.2。

2、進入/home/hadoop/hadoop-1.1.2/src/contrib目錄，將build-contrib.xml復制到/home/hadoop/hadoop-1.1.2/src/contrib/eclipse-plugin目錄下。

將

<property name="root" value="${basedir}"/>

<property name="hadoop.root" location="${root}/../../../"/>

替換為

<property name="root" value="/home/hadoop/hadoop-1.1.2/src/contrib/eclipse-plugin"/>

<property name="eclipse.home" location="/home/hadoop/eclipse"/>

<property name="version" value="1.1.2"/>

<property name="hadoop.root" location="/home/hadoop/hadoop-1.1.2"/>

3、修改 /home/hadoop/hadoop-1.1.2/src/contrib/eclipse-plugin下的build.xml文件

<import file="../build-contrib.xml"/>

改為

<import file="build-contrib.xml"/>

<pathelement location="${hadoop.root}/build/classes"/>

后插入

<pathelement location="${hadoop.root}/hadoop-core-1.1.2.jar"/>

把

<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"/>

替換為

<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" 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="${hadoop.root}/lib/commons-lang-2.4.jar" todir="${build.dir}/lib" verbose="true"/>

<copy file="${hadoop.root}/lib/jackson-core-asl-1.8.8.jar" todir="${build.dir}/lib" verbose="true"/>

<copy file="${hadoop.root}/lib/jackson-mapper-asl-1.8.8.jar" todir="${build.dir}/lib" verbose="true"/>

<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" 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="${hadoop.root}/lib/commons-lang-2.4.jar" todir="${build.dir}/lib" verbose="true"/>

<copy file="${hadoop.root}/lib/jackson-core-asl-1.8.8.jar" todir="${build.dir}/lib" verbose="true"/>

<copy file="${hadoop.root}/lib/jackson-mapper-asl-1.8.8.jar" todir="${build.dir}/lib" verbose="true"/>

4、修改：MANIFEST.MF文件。目錄：/home/hadoop/hadoop-1.1.2/src/contrib/eclipse-plugin\META-INF

Bundle-ClassPath那一欄加入如下信息：

Text代碼

Bundle-ClassPath: classes/,

lib/hadoop-core.jar,

lib/commons-cli-1.2.jar,

lib/commons-configuration-1.6.jar,

lib/commons-httpclient-3.0.1.jar,

lib/commons-lang-2.4.jar,

lib/jackson-core-asl-1.8.8.jar,

lib/jackson-mapper-asl-1.8.8.jar

5、進入/home/hadoop/hadoop-1.1.2/src/contrib/eclipse-plugin目錄，使用Ant進行編譯。

6、生成的插件包在/home/hadoop/hadoop-1.1.2/build/contrib/eclipse-plugin目錄下，

復制/home/hadoop/hadoop-1.1.2/build/contrib/eclipse-plugin/hadoop-eclipse-plugin-1.1.2.jar 到 eclipse安裝目錄/plugins/下
