编译准备
1、下载所需的软件
先去官网下载hadoop2.8.0源码并解压,打开解压目录下的BUILDING.txt,编译过程和需要的软件其实就是根据这个文档里的描述来的。
Requirements:
* Unix System
* JDK 1.7+
* Maven 3.0 or later
* Findbugs 1.3.9 (if running findbugs)
* ProtocolBuffer 2.5.0
* CMake 2.6 or newer (if compiling native code), must be 3.0 or newer on Mac
* Zlib devel (if compiling native code)
* openssl devel ( if compiling native hadoop-pipes and to get the best HDFS encryption performance )
* Jansson C XML parsing library ( if compiling libwebhdfs )
* Linux FUSE (Filesystem in Userspace) version 2.6 or above ( if compiling fuse_dfs )
* Internet connection for first build (to fetch all Maven and Hadoop dependencies)

这是编译所需要的软件,下载戳这里。
包括:
- JDK1.7+
- maven 3.0 or later
- findbugs 1.3.9
- protocolBuffer 2.5.0
- cmake 2.6
- zlib-devel
- openssl-devel
根据网友的资料,也需要安装autoconf automake gcc等。
2、安装软件
1> 安装JDK1.7并配置环境变量,这里就不赘述了,具体看前面的文档。
2> 安装各种库
yum -y install svn ncurses-devel gcc*
yum -y install lzo-devel zlib-devel autoconf automake libtool cmake openssl-devel

3> 安装maven
解压安装并配置环境变量,具体目录结构看前面的博客。
tar zxvf apache-maven-3.3.9-bin.tar.gz
vi /etc/profile

在profile
文件末尾追加
export MAVEN_HOME=/home/toto/software/apache-maven-3.3.9 export MAVEN_OPTS="-Xms256m -Xmx512m" (可以不设置) export PATH=$PATH:$MAVEN_HOME/bin 进入/home/toto/software/apache-maven-3.3.9/conf,修改settings.xml中临时产生的本地maven库的位置 /home/toto/software/repo
保存并使环境变量生效,
source /etc/profile
,输入
mvn -version
,有下面输出结果则安装并配置正确。
[root@hadoop ~]# mvn -version

开始编译
首先保证主机能上网(虚拟机怎么上网的点这里),在编译过程中网络保持畅通;进入到hadoop2.8.0源码的解压目录下,输入下面命令:
cd /home/toto/software/hadoop-2.8.0-src
mvn package -Pdist,native -DskipTests -Dtar
- 1
- 1
或者这个
cd /home/toto/software/hadoop-2.8.0-src
mvn package -Pdist,native,docs,src -DskipTests -Dtar
- 1
- 1
前面只编译本地代码,后者编译本地代码和文档,因此前者速度较快。
接下来就是漫长的等待,等出现这个就说明编译成功。

编译好的文件在../hadoop-dist/target/hadoop-2.8.0.tar.gz
下。
最后编译后出的效果:
cd /home/toto/software/hadoop-2.8.0-src/hadoop-dist/target
编译中遇到的问题
错误1
Connection to http://repo.maven.apache.org refused
表示连接maven远程仓库拒绝,此时再运行一下编译命令,就会接着下载jar包。
错误2
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project hadoop-nfs: Compilation failure: Compilation failure:
[ERROR] /home/hadoop/toolkits/hadoop-2.7.1-src/hadoop-common-project/hadoop-nfs/src/main/java/org/apache/hadoop/oncrpc/XDR.java:[23,30] package org.jboss.netty.buffer does not exist

这个错误估计很少遇到,这是因为我嫌repo.maven.apache.org这个网站比较慢,更改的第三方镜像,导致maven中的settings文件配置错误,后来采用默认的就行,虽然慢点。
错误3
[ERROR] around Ant part ..."/opt/soft/hadoop-2.7.1-src/hadoop-hdfs-project/hadoop-hdfs-httpfs/target" executable="sh" failonerror="true">... @ 10:123 in /opt/soft/hadoop-2.7.1-src/hadoop-hdfs-project/hadoop-hdfs-httpfs/target/antrun/build-main.xml

这是由于tomcat的apache-tomcat-6.0.41.tar.gz包太大,没有下载完整,可以到.../hadoop-2.7.1-src/hadoop-hdfs-project/hadoop-hdfs-httpfs/downloads/apache-tomcat-6.0.41.tar.gz
这个目录下,删除重新下载。
提醒:
1、有时候编译过程中会出现下载某个包的时间太久,这是由于连接网站的过程中会出现假死,此时按ctrl+c
,重新运行编译命令。
2、如果出现缺少了某个文件的情况,则要先清理maven(使用命令 mvn clean
) 再重新编译。
====================================
写在最后:
经过了较长时间的折磨,终于成功,可能还是自己比较菜吧,有编译不成功的欢迎留言探讨。
