本文详细介绍了Hadoop的两种编译方式：手动编译和docker编译。手动编译需自行安装依赖，如JDK、maven等，并调整maven仓库以提高下载速度。docker编译则通过预置依赖的镜像简化流程，一键部署编译环境。

Hadoop现在提供了两种源代码编译方式，手动编译和docker编译。

手动编译：自己手动安装Hadoop编译所需的各种依赖包，缺点是工作量较大且存在依赖冲突的风险。
docker编译：编译Hadoop所需的依赖会提前打入docker镜像，缺点是需要额安装docker，优点是一键部署编译环境，不用担心各种库不兼容等问题，编译失败率低。

一. 手动编译

1.编译环境与依赖

操作系统：centos7
JDK：1.8
maven：3.8.6
cmake：3.13.0
protobuf：2.5.0
hadoop：3.2.4

2.安装依赖

1.安装gcc，g++

yum install -y gcc
yum install -y gcc-c++
# 验证是否安装成功
gcc -v
g++ -v

2.安装JDK

tar xf jdk1.8.0_144.tar.gz -C /opt/java
# 添加环境变量
vim /etc/profile
export JAVA_HOME=/opt/java/jdk1.8.0_144
export PATH=$PATH:$JAVA_HOME/bin
# 验证是否安装成功
source /etc/profile
java -version

3.安装maven

tar vf apache-maven-3.8.6.tar.gz -C /opt
# 添加环境变量
vim /etc/profile
export MAVEN_HOME=/opt/apache-maven-3.8.6
export PATH=$PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin
# 验证是否安装成功
source /etc/profile
mvn -v

4.安装cmake

tar xf cmake-3.13.0.tar.gz -C /opt
cd /opt/cmake-3.13.0
./bootstrap
# 编译并安装
gmake & gmake install
# 验证是否安装成功
cmake -version

5.安装Protobuf

tar xf protobuf-2.5.0.tar.gz -C /opt
cd /opt/protobuf-2.5.0
./configure
# 编译并安装
make &  make install
# 验证是否安装成功
protoc --version

3.编译

1.解压hadoop源代码包

tar xf  hadoop-3.2.4-src.tar.gz -C /root

2.修改maven仓库地址
默认的maven仓库地址下载速度可能比较慢，建议更换成阿里云的镜像。

vim /opt/apache-maven-3.8.6/conf/settings.xml
# 添加如下内容
<mirror>
   <id>alimaven-central</id>
   <mirrorOf>central</mirrorOf>
   <name>aliyun maven</name>
   <url>https://maven.aliyun.com/nexus/content/repositories/central/</url>
</mirror>
<mirror>
   <id>alimaven</id>
   <name>aliyun maven</name>
   <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
   <mirrorOf>central</mirrorOf>
</mirror>
<mirror>
   <id>jboss-public-repository-group</id>
   <mirrorOf>central</mirrorOf>
   <name>JBoss Public Repository Group</name>
   <url>http://repository.jboss.org/nexus/content/groups/public</url>
</mirror>

3.编译

cd /root/hadoop-3.2.4-src
# 执行mvn构建
mvn clean package -Pdist -DskipTests -Dtar

如果中途编译失败，请重复执行这个命令，直到成功，一般第一次编译会比较费时间，耐心等待即可，编译成功如下所示。
