Hadoop源码编译，hadoop-2.4.1+Lubuntu（Ubuntu）

先从Hadoop官网上面下载最新的源码，我的是2.4.1版本。

1、编译环境：

按照build.txt要求，安装jdk, maven, protocbuff, cmake，基本的依赖包gcc,gcc-c++,make

jdk在官网上下载然后安装，注意在、/etc/profile添加路径，用java -version验证

maven我是直接用apt-geit install安装的只有3.0.5版本不过已经够用了，而且这样安装好像自己配置好了，可以用mvn -v验证安装

protocbuff这个切记不要用apt-gei install 安装，否则会出现找不到的情况，下载地址:https://code.google.com/p/protobuf/downloads/list，要下载2.5.0版本噢，安装参照说明书readme.txt

tar -xvf protobuf-2.5.0.tar.bz2  
cd protobuf-2.5.0  
./configure --prefix=/usr  //很重要,否则找不到protoc
make

make check

make install  

验证protoc --version

2、编译hadoop
a.官方下载hadoop源码
b.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,
在里添加，原本的不要动
 
  nexus-osc  
  *  
  Nexusosc  
  http://maven.oschina.net/content/groups/public/  
 
c，在内新添加
 
       jdk-1.7  
         
         1.4  
         
         
           
           nexus  
           local private nexus  
           http://maven.oschina.net/content/groups/public/  
             
             true  
             
             
             false  
             
           
         
         
           
           nexus  
          local private nexus  
           http://maven.oschina.net/content/groups/public/  
             
             true  
             
             
             false  
             
           
         
 
d.编译clean

进入Hadoop源码目录
cd /opt/hadoop-2.4.1-src
mvn clean install  

e、成功后就直接可以编译源码了

mvn package -Pdist,native -DskipTests -Dtar
f、 如果遇到下面的 错误

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.3:test (default-test) on project hadoop-common: There are test failures.

[ERROR] 
[ERROR] Please refer to /opt/hadoop-2.4.1-src/hadoop-common-project/hadoop-common/target/surefire-reports for the individual test results.
[ERROR] -> [Help 1]
[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR] 
[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoFailureException
[ERROR] 
[ERROR] After correcting the problems, you can resume the build with the command
[ERROR]   mvn -rf :hadoop-common
一是命令行，
mvn clean package -Dmaven.test.skip=true
二是写入pom文件(我用的是这种)
 
        org.apache.maven.plugins  
        maven-surefire-plugin  
        2.4.2  
         
          true  
         
 

g、 如果再次编译遇到下面的 错误

遇到报错Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run (make) on project hadoop-common:
这是没有安装zlib1g-dev的关系，这个可以 使用apt-get安装

h、 如果再次编译遇到下面的错误

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run (dist) on project hadoop-hdfs-httpfs: An Ant BuildException has occured: exec returned: 2 -> [Help 1]

[ERROR] For more information about the errors and possible solutions, please read the following articles:

[ERROR] [Help 1] http://cwiki.apache.org/confluen ... oExecutionException
[ERROR] 
[ERROR] After correcting the problems, you can resume the build with the command
[ERROR]   mvn -rf :hadoop-hdfs-httpfs

这是因为/home/pory/workplace/hadoop-2.4.1-src/hadoop-hdfs-project/hadoop-hdfs-httpfs/downloads目录下的文件没有下载完全，可以手动下一份匹配版本的文件放在下面，我的是在http://archive.apache.org/dist/tomcat/tomcat-6/v6.0.36/bin/

i、 如果再次编译遇到下面的错误

 Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (make) on

 project hadoop-pipes: An Ant BuildException has occured: exec returned: 1

[ERROR] around Ant part ...tools/hadoop-pipes/target/native" executable="cmake" failοnerrοr="true">... @ 5:131 in

 /home/pory/workplace/hadoop-2.4.1-src/hadoop-tools/hadoop-pipes/target/antrun/build-

main.xml

[ERROR] -> [Help 1]

这是没有装，openssl-devl, ncurses-devel, libssl-dev依次安装
j、 现在可以进行编译了
mvn package -Pdist,native -DskipTests -Dtar

编译后的路径在:hadoop-2.4.1-src/hadoop-dist/target/

总结：hadoop编译出问题一般是环境缺少相应的依赖库，首先严格按照说明安装相应的库版本号也必须符合要求。其次如果真是出问题了，可以用mvn -X查看调试信息，看是哪里出问题，一般都能找到解决方法
