基于http://www.cnblogs.com/manhua/上的作品创作。

实验环境：Ubuntu12.04.3 x64

编译前需要安装：

JDK7u45mavenProtocfindbugs等等，需要保持联网状态

所有安装文件全部放在当前用户目录~。

install java(64位) 安装方法参见此文

other

    sudo apt-get install g++
    sudo apt-get install cmake
    sudo apt-get install zlib1g.dev   //An Ant BuildException has occured: exec returned: 1
    sudo apt-get install libssl-dev   //openssl problem

install findbugs(需配置环境，见后文)

wget http://jaist.dl.sourceforge.net/project/findbugs/findbugs/2.0.3/findbugs-2.0.3.tar.gz
sudo tar -zxvf findbugs-2.0.3.tar.gz  -C  /opt

install maven(需配置环境，见后文)

wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.1.1/binaries/apache-maven-3.1.1-bin.tar.gz
sudo tar zxvf apache-maven-3.1.1-bin.tar.gz -C  /opt
cd /opt/apache-maven-3.1.1/conf
sudo gedit settings.xml

由于maven国外服务器可能连不上，先给maven配置一下国内镜像，在maven目录下，conf/settings.xml,在<mirrors></mirros>里添加：

   <mirror>
        <id>nexus-osc</id>
         <mirrorOf>*</mirrorOf>
     <name>Nexusosc</name>
     <url>http://maven.oschina.net/content/groups/public/</url>
   </mirror>

同样，在<profiles></profiles>内新添加：

   <profile>
       <id>jdk-1.7</id>
       <activation>
         <jdk>1.7</jdk>
       </activation>
       <repositories>
         <repository>
           <id>nexus</id>
           <name>local private nexus</name>
           <url>http://maven.oschina.net/content/groups/public/</url>
           <releases>
             <enabled>true</enabled>
           </releases>
           <snapshots>
             <enabled>false</enabled>
           </snapshots>
         </repository>
       </repositories>
       <pluginRepositories>
         <pluginRepository>
           <id>nexus</id>
          <name>local private nexus</name>
           <url>http://maven.oschina.net/content/groups/public/</url>
           <releases>
             <enabled>true</enabled>
           </releases>
           <snapshots>
             <enabled>false</enabled>
           </snapshots>
         </pluginRepository>
       </pluginRepositories>
     </profile>

install protobuf(编译安装，注意hadoop2.2.0要求protoc是2.5版本，在code.google上的protobuf-2.5.0.tar.gz格式的安装后为2.4.1，建议下载zip版)

cd ~
 wget https://code.google.com/p/protobuf/downloads/detail?name=protobuf-2.5.0.zip&can=2&q=
unzip protobuf-2.5.0.zip
cd  protobuf-2.5.0/
sudo ./configure --prefix=/usr
sudo make clean //此命令为了避免出现cannot install `libprotoc.la' to a directory not ending in /opt/protoc/lib的错误
sudo make && make install

setup env

sudo gedit /etc/profile

#Java
export JAVA_HOME=/usr/local/java/jdk1.7.0_45
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH 
export CLASSPATH=$CLASSPATH:.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

#FINDBUGS

export PATH=$FINDBUGS_HOME/bin:$PATH

source /etc/profile

compile

edit hadoop-2.2.0-src/pom.xml@line221 3.0->3.3

cd ~/hadoop-2.2.0-src/
mvn clean package -Pdist,native,docs -DskipTests -Dtar
//编译中途出错修正后可从指定点开始继续编译，修改最后一个参数即可。如出现hadoop-hdfs/target/findbugsXml.xml does not exist则从该命令删除docs参数再运行mvn package -Pdist,native -DskipTests -Dtar -rf :hadoop-pipes

漫长等待吧~在虚拟机也就用了半个小时

[exec] $ tar cf hadoop-2.2.0.tar hadoop-2.2.0
[exec] $ gzip -f hadoop-2.2.0.tar
