hadoop-2.0.0-mr1-cdh4.2.2 eclipse插件安装

1. 下载hadoop-2.0.0-cdh4.2.2.tar.gz

2.解压tar -zxvf hadoop-2.0.0-cdh4.2.2.tar.gz

3.进入目录./hadoop-2.0.0-mr1-cdh4.2.2/src/contrib，修改build-contrib.xml文件

<!-- 原内容为off -->

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

4.进入目录./hadoop-2.0.0-mr1-cdh4.2.2/src/contrib/eclipse-plugin

(1)修改build.xml（红色部分为修改或添加的内容）

<project default="jar" name="eclipse-plugin">

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

<property name="eclipse.home" location="eclipse安装目录" />

<property name="version" value="2.0.0-cdh4.2.2" />

。。。。

<path id="classpath">

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

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

<fileset dir="${hadoop.root}">

<include name="**/*.jar" />

</fileset>

<path refid="eclipse-sdk-jars"/>

</path>

。。。

<target name="compile" depends="init, ivy-retrieve-common" unless="skip.contrib">

<echo message="contrib: ${name}"/>

<javac

encoding="${build.encoding}"

srcdir="${src.dir}"

includes="**/*.java"

destdir="${build.classes}"

debug="${javac.debug}"

deprecation="${javac.deprecation}"

includeantruntime="on">

<classpath refid="classpath"/>

</javac>

</target>

<!-- Override jar target to specify manifest -->

<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="${hadoop.root}/hadoop-core-2.0.0-mr1-cdh4.2.2.jar" tofile="${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="${hadoop.root}/lib/commons-httpclient-3.1.jar" tofile="${build.dir}/lib/commons-httpclient.jar" verbose="true"/>

<copy file="${hadoop.root}/lib/commons-lang-2.5.jar" tofile="${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"/>

<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)修改build.properties（添加如下内容）

reactor.repo=https://repository.cloudera.com/content/repositories/snapshots

5.在当前目录下运行ant命令

6.将生成的hadoop-eclipse-plugin-2.0.0-cdh4.2.2.jar拷贝到Eclipse安装目录的plugins目录下，运行Eclipse
