building hadoop2.4.1 on centos7[在centos7上面构建hadoop2.4.1]

　　本文介绍在centos7上面通过hadoop2.4.1源码构建hadoop distribution 版本，即hadoop的运行版本。

　　为何要自己building，而不用Apache的distribution 【bin】版本，因为hadoop涉及到Linux系统的底层实现，如：

　　　　hadoop fs -ls /

　　通过 java Native 实现，故应为 native的相关lib。【个人认为的一点】

　　　　文件目录解释：

• 　hadoop
  • hadoop-2.4.1.tar.gz 本人通过在centos7上构建的distribution版本，可以直接下载并配置，然后运行即可，参考文章：
  • hadoop-2.4.1-src.tar.gz hadoop的源代码
• 　relative_tools
  • maven　　【只需要配置 MAVEN_HADOOP 的环境变量】
  • protocolbuf   [即：google protocolBUffer]，需要自己构建，并检查protocolbuf是否已配置环境变量
  • findbugs  需要自己构建，并检查protocolbuf是否已配置环境变量
  • Cmake 自己搜索，并构建配置环境变量

  • Requirements:
    
    * Unix System
    * JDK 1.6+
    * Maven 3.0 or later
    * Findbugs 1.3. (if running findbugs)
    * ProtocolBuffer 2.5.
    * CMake 2.6 or newer (if compiling native code)
    * Internet connection for first build (to fetch all Maven and Hadoop dependencies)
    
    ----------------------------------------------------------------------------------
    Maven build goals:
    
     * Clean                     : mvn clean
     * Compile                   : mvn compile [-Pnative]
     * Run tests                 : mvn test [-Pnative]
     * Create JAR                : mvn package
     * Run findbugs              : mvn compile findbugs:findbugs
     * Run checkstyle            : mvn compile checkstyle:checkstyle
     * Install JAR in M2 cache   : mvn install
     * Deploy JAR to Maven repo  : mvn deploy
     * Run clover                : mvn test -Pclover [-DcloverLicenseLocation=${user.name}/.clover.license]
     * Run Rat                   : mvn apache-rat:check
     * Build javadocs            : mvn javadoc:javadoc
     * Build distribution        : mvn package [-Pdist][-Pdocs][-Psrc][-Pnative][-Dtar]
     * Change Hadoop version     : mvn versions:set -DnewVersion=NEWVERSION
    
     Build options:
    
      * Use -Pnative to compile/bundle native code
      * Use -Pdocs to generate & bundle the documentation in the distribution (using -Pdist)
      * Use -Psrc to create a project source TAR.GZ
      * Use -Dtar to create a TAR with the distribution (using -Pdist)
    
    ----------------------------------------------------------------------------------
    Importing projects to eclipse
    
    When you import the project to eclipse, install hadoop-maven-plugins at first.
    
      $ cd hadoop-maven-plugins
      $ mvn install
    
    Then, generate eclipse project files.
    
      $ mvn eclipse:eclipse -DskipTests
    
    At last, import to eclipse by specifying the root directory of the project via
    [File] > [Import] > [Existing Projects into Workspace].
    
    ----------------------------------------------------------------------------------
    Building distributions:
    
    Create binary distribution without native code and without documentation:
    
      $ mvn package -Pdist -DskipTests -Dtar
    
    Create binary distribution with native code and with documentation:
    
      $ mvn package -Pdist,native,docs -DskipTests -Dtar
    
    Create source distribution:
    
      $ mvn package -Psrc -DskipTests
    
    Create source and binary distributions with native code and documentation:
    
      $ mvn package -Pdist,native,docs,src -DskipTests -Dtar
    
    Create a local staging version of the website (in /tmp/hadoop-site)
    
      $ mvn clean site; mvn site:stage -DstagingDirectory=/tmp/hadoop-site

• 只要上述的Linux系统、cmake、maven、findbuds、protocolbuf、网络连通、java都已构建/安装成功后等条件满足后，就在hadoop源代码目录运行代码区的着色区域
