64位Ubuntu 编译 hadoop源码

本人下载了最新版的ubuntu64（14.04）位桌面版系统，在安装hadoop2.6.0时，由于官方的hadoop是在32位机子上编译的，故需下载hadoop源码进行编译。

准备：hadoop-2.6.0-src

           jdk1.7.0_75(由于最新版的jdk是1.8.0_31版本的，而我在用这个版本编译hadoop时出现了问题，后来发现1.8.0是在hadoop出来之后出来的，所以可能有些不支持，故建议用1.7.0版本的)

1、安装JDK

安装jdk的方式大家可以网上搜一下，或者通过这个链接http://www.cnblogs.com/yulijunzj/p/4253748.html查看，方式是一样的

2、安装maven

sudo apt-get install maven

安装完后可以查看maven版本信息

mvn --version

3、安装openssh

sudo apt-get install openssh-server

4、安装依赖库

sudo apt-get install g++ autoconf automake libtool cmake zlib1g-dev pkg-config libssl-dev

5、安装protoc

sudo apt-get install protobuf-compiler

安装完后可以查看版本信息

protoc --version

6、开始编译，进入HADOOP源代码目录 hadoop-2.6.0-src，执行：

mvn clean package -Pdist,native -DskipTests -Dtar

 7、编译成功，结果如下：

问题：

本人在编译hadoop时主要遇到了三个问题，导致多次编译不成功。

1)在编译之前安装maven时他默认的java不是之前装的，并且我之前装得jdk的版本是1.8.0_31,发现与hadoop2.6.0存在不兼容现象，需要去该hadoop的代码，比较麻烦。

解决办法：该用jdk1.7.0_65版本，在改完版本后，我需要更改默认版本：

    sudo update-alternatives --config java  
    sudo update-alternatives --config javac 
    sudo update-alternatives --config javadoc  
    sudo update-alternatives --config javah

2)遇到无法删除target文件夹的错误

解决方法：

chown 用户名 文件夹/ -R

3)就是由于网速过慢，时不时就直接失败

解决方法：

重复的执行第六步。
