Alluxio编译

Alluxio的二进制发布包，是依赖于具体的hadoop版本的，截至本文撰写时，直接下载的alluxio二进制安装包是对应于hadoop 2.2.0的，如果你的hadoop基础环境不是这个版本，那就需要根据实际情况，下载alluxio源码，执行编译，进而制作出实际可用的安装文件。

下面就概要说明alluxio的整个编译过程和编译成果物的确认。

一、准备工作：

1. 保证你的编译环境是Linux系列（Linux或者是Mac OS X），如果你是Windows系统，可以使用虚拟机解决方案。

2. 保证你的编译环境的OS是可以联网的（编译时候需要依赖包下载和其他网络通讯）

3. 安装Java7或者以上版本的JDK

4. 安装Maven

5. 安装Git（如果你是直接下载源码包的方式，此项可选）

二、编译开始：

1. 从github克隆(git clone)Alluxio源码（并切换到你想要编译的版本号）

git clone git://github.com/alluxio/alluxio.gitcd alluxiogit checkout v1.4.0

2. 执行编译

根据你的hadoop基础环境中hadoop的版本号，来设定Alluxio工程中的<hadoop.version>属性值，比如你的环境中部署的是Hadoop2.6.5，请将alluxio工程跟目录下的pom文件中的<hadoop.version>2.2.0</hadoop.version>修改为<hadoop.version>2.6.5</hadoop.version>，保存后执行如下命令：

mvn clean package -DskipTests

另一种方式，不需要修改上述pom文件，可直接执行如下命令：

mvn -Dhadoop.version=2.6.5 clean package -DskipTests

编译成功后，你会看到如下信息：

3. 查看编译成果物

编译成功后，你会在assembly/target目录下看到alluxio-assemblies-1.4.0-jar-with-dependencies.jar，在core/client/target目录下看到 alluxio-core-client-1.4.0-jar-with-dependencies.jar

至此，你已经完成了Alluxio的源码编译，接下来就可以执行安装配置和启动过程。
