如何在CentOS6.5下编译64位的Hadoop2.x

hadoop2.x在apache官网直接下载的并没有64位直接能用的版本，如果我们想在64位系统使用，那么就需要重新编译hadoop，否则直接使用32位的hadoop运行在64位的系统上，将会出现一些库不兼容的异常。如下图所示，最直接的一个异常:



在这之前，散仙先用一个表格来描述下散仙的编译的环境的状况:

序号	描述	备注
1	centos6.5系统64位	linux环境
2	Apache Ant1.9	ant编译
3	Apache Maven3.2.1	maven打包部署
4	gcc,gcc-c++,make	依赖库
5	protobuf-2.5.0	序列化库
6	JDK1.7	JAVA 环境
7	Hadoop2.2.0源码包	官网下载
8	屌丝工程师一名	主角
9	hadoop交流群376932160	技术交流

下面进入正题，散仙的环境是在centos下，所以大部分安装编译依赖库，都可以很方便的使用yum命令来完成。

1,安装gcc，执行如下的几个yum命令即可

yum -y install gcc
yum install -y  bzip2-devel
yum -y install gcc-c++
yum install make
yum install autoconf automake libtool cmake ncurses-devel openssl-devel gcc*

2,安装JDK,并设置环境变量，完成后测试安装成功否

[root@ganglia ~]# java -version
java version "1.5.0"
gij (GNU libgcj) version 4.4.7 20120313 (Red Hat 4.4.7-4)

warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
[root@ganglia ~]# 

3， 安装Maven，安装完成后测试安装与否

[root@ganglia ~]# mvn -v
Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-15T01:37:52+08:00)
Maven home: /usr/local/maven
Java version: 1.7.0_25, vendor: Oracle Corporation
Java home: /usr/local/jdk1.7.0_25/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-431.el6.x86_64", arch: "amd64", family: "unix"
[root@ganglia ~]# 

4, 安装Ant， 安装完成后，依旧测试成功与否

[root@ganglia ~]# ant -version
Apache Ant(TM) version 1.9.4 compiled on April 29 2014
[root@ganglia ~]# 

5,安装protobuf，安装方式，从官网下载tar.gz的包点击下载，并上传到linux上解压，然后进入根目录下，执行如下的几个命令:
wget https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.bz2

./configure 
make 
make check
make install

然后，执行如下命令，进行测试安装成功与否

[root@ganglia protobuf-2.5.0]# protoc
Missing input file.
[root@ganglia protobuf-2.5.0]# 

6,从hadoop官网下载hadoop2.2.0的版本的源码的src的包，并查看目录

[root@ganglia ~]# cd hadoop-2.2.0-src
[root@ganglia hadoop-2.2.0-src]# ll

[root@ganglia hadoop-2.2.0-src]# 

7，修改/root/hadoop-2.2.0-src/hadoop-common-project/hadoop-auth/pom.xml文件，增加，补丁内容，这部分是hadoop2.2.0的bug，如果是其他的2.x的版本，可以视情况而定，内容如下：

  <dependency>
      <groupId>org.mockito</groupId>
      <artifactId>mockito-all</artifactId>
      <scope>test</scope>
    </dependency>
	<!--新增的内容开始 -->
	<dependency>
		<groupId>org.mortbay.jetty</groupId>
		    <artifactId>jetty-util</artifactId>
		    <scope>test</scope>
	</dependency>
	<!--新增的内容结束 -->
    <dependency>
      <groupId>org.mortbay.jetty</groupId>
      <artifactId>jetty</artifactId>
      <scope>test</scope>
    </dependency>

8，修改完毕后，回到hadoop-2.2.0-src的跟目录下执行编译打包命令:

mvn clean
mvn package -Pdist,native -DskipTests -Dtar

然后等待半个小时左右的编译时间，网速快的话，时间可能会更短，编译完成后，输出的打包信息如下：

至此，我们的编译已经，成功完成，然后，我们就可以使用在target目录下，编译生成的hadoop新的tar.gz包，来部署我们的hadoop集群。
