自己编译的cloudera cdh3u2 eclipse plugin

操作系统:ubuntu10.10 32bit用户：xcloudHadoop:hadoop-0.20.2-cdh3u2 (安装目录：/home/xcloud/cdh3/hadoop-0.20.2-cdh3u2)eclipse:eclipse3.7(indigo) >> eclipse3.5(galileo)编译好到eclipse plugin，eclipse3.7(indigo)版本跑不起来，抛6.错误 中a错误，更换版本为eclipse3.5(galileo)后，可正常使用。1.hadoop-eclipse-plugin源码将hadoop-eclipse-plugin源码拷贝到eclipse工程目录下源码位置：$HADOOP_HOME/src/contrib/eclipse-plugin2.build-contrib.xml拷贝$HADOOP_HOME/src/contrib/build-contrib.xml到eclipse插件工程根目录下

a.新增一属性--eclipse-home dir<property name="eclipse.home" value="/opt/eclipse"/>

b.新增属性

<property name="version" value="0.20.2-cdh3u2"/>

c.修改 

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

  为 :

<property name="hadoop.root" location="/home/xcloud/cdh3/hadoop-0.20.2-cdh3u2/"/>

3.build.xml

a.修改

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

 为   

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

b.修改classpath
fileset指向hadoop安装目录下到jar文件

 <path id="classpath">    <pathelement location="${build.classes}"/>    <pathelement location="${hadoop.root}/build/classes"/>    <path refid="eclipse-sdk-jars"/>  <fileset dir="/home/xcloud/cdh3/hadoop-0.20.2-cdh3u2/">       <include name="*.jar"/>    </fileset>     </path>

c.拷贝

sudo cp $HADOOP_HOME//ivy/ivy-2.0.0-rc2.jar /home/xcloud/cdh3/sudo cp $HADOOP_HOME//ivy/ivy-2.0.0-rc2.jar /home/xcloud/cdh3/

修改

<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"/>

    
为

<copy file="/home/xcloud/cdh3/hadoop-core-${version}.jar" tofile="${build.dir}/lib/hadoop-core.jar" verbose="true"/><copy file="/home/xcloud/cdh3/ivy-2.0.0-rc2.jar"  tofile="${build.dir}/lib/commons-cli-${commons-cli.version}.jar" verbose="true"/>

4.ant build

/home/xcloud/cdh3/hadoop-0.20.2-cdh3u2/build/contrib/eclipse-plugin/hadoop-eclipse-plugin-0.20.2-cdh3u2.jarcp $HADOOP_HOME/build/contrib/eclipse-plugin/hadoop-eclipse-plugin-0.20.2-cdh3u2.jar $ECLIPSE_HOME/plugins

5.打开eclipse进行hadoop目录，相关配置设置

6.错误

a.2011-12-30 15:06:38,604 WARN org.apache.hadoop.ipc.Server: Incorrect header or version mismatch from 10.45.46.123:44614 got version 3 expected version 4
无解！
后更换eclipse版本为eclipse-jee-galileo-linux-gtk.tar.gz 一切正常起来，估计跟eclipse版本有关系。

eclipse-jee-indigo-linux-gtk.tar.gz

b.An internal error occurred during: "Map/Reduce location status updater".
org/codehaus/jackson/map/JsonMappingException,暂时不影响使用。
