## 1、背景 ##

最近在学习`hadoop`，此篇文章简单记录一下通过源码来编译`hadoop`。为什么要重新编译`hadoop源码`，是因为为了匹配不同操作系统的本地库环境。

## 2、编译源码 ##

### 2.1 下载并解压源码 ###

![源码路径][7ef1e86b60e24717b50fb373e7ac6814.png]

[root@hadoop01 ~]# mkdir /opt/hadoop
    [root@hadoop01 ~]# cd /opt/hadoop/
    [root@hadoop01 hadoop]# wget https://archive.apache.org/dist/hadoop/common/hadoop-3.3.4/hadoop-3.3.4-src.tar.gz
    [root@hadoop01 hadoop]# tar -zxvf hadoop-3.3.4-src.tar.gz
    [root@hadoop01 hadoop]# rm -rvf hadoop-3.3.4-src.tar.gz

### 2.2 查看编译hadoop必要的环境 ###

[root@hadoop01 hadoop]# pwd
    /opt/hadoop
    [root@hadoop01 hadoop]# cd hadoop-3.3.4-src/
    [root@hadoop01 hadoop-3.3.4-src]# cat BUILDING.txt
    Build instructions for Hadoop
    
    ----------------------------------------------------------------------------------
    Requirements:
    
    * Unix System
    * JDK 1.8
    * Maven 3.3 or later
    * Protocol Buffers 3.7.1 (if compiling native code)
    * CMake 3.1 or newer (if compiling native code)
    * Zlib devel (if compiling native code)
    * Cyrus SASL devel (if compiling native code)
    * One of the compilers that support thread_local storage: GCC 4.8.1 or later, Visual Studio,
      Clang (community version), Clang (version for iOS 9 and later) (if compiling native code)
    * openssl devel (if compiling native hadoop-pipes and to get the best HDFS encryption performance)
    * Linux FUSE (Filesystem in Userspace) version 2.6 or above (if compiling fuse_dfs)
    * Doxygen ( if compiling libhdfspp and generating the documents )
    * Internet connection for first build (to fetch all Maven and Hadoop dependencies)
    * python (for releasedocs)
    * bats (for shell code testing)
    * Node.js / bower / Ember-cli (for YARN UI v2 building)
    
    ----------------------------------------------------------------------------------

可以看到需要`JDK1.8及以上、maven3.3及以上等等`

### 2.3 安装JDK ###

需要注意JDK的版本,参考这个文档。[https://cwiki.apache.org/confluence/display/HADOOP/Hadoop+Java+Versions][https_cwiki.apache.org_confluence_display_HADOOP_Hadoop_Java_Versions]

### 2.4 安装maven ###

[root@hadoop01 hadoop]# wget https://dlcdn.apache.org/maven/maven-3/3.9.0/binaries/apache-maven-3.9.0-bin.tar.gz
    [root@hadoop01 hadoop]# tar -zxvf apache-maven-3.9.0-bin.tar.gz -C /usr/local
    # 编辑环境变量
    [root@hadoop01 hadoop]# vim /etc/profile
    # 配置maven
    export M2_HOME=/usr/local/apache-maven-3.9.0
    export PATH=${M2_HOME}/bin:$PATH
    [root@hadoop01 hadoop]# source /etc/profile
    # 查看maven的版本
    [root@hadoop01 apache-maven-3.9.0]# mvn -version
    Apache Maven 3.9.0 (9b58d2bad23a66be161c4664ef21ce219c2c8584)
    Maven home: /usr/local/apache-maven-3.9.0
    Java version: 1.8.0_333, vendor: Oracle Corporation, runtime: /usr/local/jdk8/jre
    Default locale: zh_CN, platform encoding: UTF-8
    OS name: "linux", version: "5.11.12-300.el7.aarch64", arch: "aarch64", family: "unix"
    # 配置aliyun镜像加速访问
    [root@hadoop01 hadoop]# vim /usr/local/apache-maven-3.9.0/conf/settings.xml
    <mirrors>
         <mirror>
               <id>alimaven</id>
               <name>aliyun maven</name>
               <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
               <mirrorOf>central</mirrorOf>
          </mirror>
    </mirrors>

### 2.5 安装编译相关的依赖 ###

[root@hadoop01 hadoop]# yum install gcc gcc-c++ make autoconf automake libtool curl lzo-devel zlib-devel openssl openssl-devel ncurses-devel snappy snappy-devel bzip2 bzip2-devel lzo lzo-devel lzop libXtst zlib doxygen cyrus-sasl* saslwrapper-devel* -y

### 2.6 安装cmake ###

`hadoop`要求`* CMake 3.1 or newer (if compiling native code)` cmake的版本在`3.1及其以上`。`cmake`不是必须的。  
![cmake下载][cmake]

# 卸载已有的cmake
    [root@hadoop01 hadoop]# yum erase cmake
    # 下载cmake(此处需要根据自己的操作系统进行下载)
    [root@hadoop01 hadoop]# wget https://github.com/Kitware/CMake/releases/download/v3.25.2/cmake-3.25.2.tar.gz
    [root@hadoop01 hadoop]# tar -zxvf cmake-3.25.2.tar.gz
    # 编译和安装cmake
    [root@hadoop01 cmake-3.25.2-linux-aarch64]# cd cmake-3.25.2/ && ./configure && make && make install
    # 查看cmake的版本
    [root@hadoop01 cmake-3.25.2]# cmake -version
    cmake version 3.25.2
    
    CMake suite maintained and supported by Kitware (kitware.com/cmake).

### 2.7 安装Snappy ###

`* Snappy compression (only used for hadoop-mapreduce-client-nativetask)`

# 卸载已安装的snappy
    [root@hadoop01 hadoop]# rm -rf /usr/local/lib/libsnappy* && rm -rf /lib64/libsnappy*
    [root@hadoop01 hadoop]# wget https://src.fedoraproject.org/repo/pkgs/snappy/snappy-1.1.3.tar.gz/7358c82f133dc77798e4c2062a749b73/snappy-1.1.3.tar.gz
    [root@hadoop01 snappy]# tar -zxvf snappy-1.1.3.tar.gz
    [root@hadoop01 snappy]# cd snappy-1.1.3/ && ./configure && make && make install
    [root@hadoop01 build]#

![snappy安装目录][snappy]

### 2.8 安装ProtocolBuffer ###

`* Protocol Buffers 3.7.1 (if compiling native code)` 安装3.7.1的版本

[root@hadoop01 hadoop]# wget https://github.com/protocolbuffers/protobuf/releases/download/v3.7.1/protobuf-java-3.7.1.tar.gz
    [root@hadoop01 hadoop]# tar -zxvf protobuf-java-3.7.1.tar.gz
    # 编译和安装
    [root@hadoop01 hadoop]# cd protobuf-3.7.1/ && ./autogen.sh && ./configure && make && make install
    # 验证是否安装成功
    [root@hadoop01 protobuf-3.7.1]# protoc --version
    libprotoc 3.7.1

### 2.9 编译hadoop ###

[root@hadoop01 hadoop-3.3.4-src]# pwd
    /opt/hadoop/hadoop-3.3.4-src
    [root@hadoop01 hadoop-3.3.4-src]# export MAVEN_OPTS="-Xms3072m -Xmx3072m" && mvn clean package -Pdist,native -DskipTests -Dtar -Dbundle.snappy -Dsnappy.lib=/usr/local/lib -e

此处的`mvn 命令`也可以从`BUILDING.txt`文件中获取。

![出现这个图说明编译成功了][943f5d5bc835432faf627f4ce6ce08fd.png]

### 2.10 编译后的安装包路径 ###

`hadoop-3.3.4-src/hadoop-dist/target/hadoop-3.3.4.tar.gz`

### 2.11 检测native ###

[root@hadoop01 hadoop]# tar -zxvf hadoop-3.3.4.tar.gz
    [root@hadoop01 bin]# cd hadoop-3.3.4/bin
    [root@hadoop01 bin]# ./hadoop checknative -a
    2023-02-18 16:58:39,698 INFO bzip2.Bzip2Factory: Successfully loaded & initialized native-bzip2 library system-native
    2023-02-18 16:58:39,700 INFO zlib.ZlibFactory: Successfully loaded & initialized native-zlib library
    2023-02-18 16:58:39,700 WARN erasurecode.ErasureCodeNative: ISA-L support is not available in your platform... using builtin-java codec where applicable
    2023-02-18 16:58:39,760 INFO nativeio.NativeIO: The native code was built without PMDK support.
    Native library checking:
    hadoop:  true /opt/hadoop/hadoop-3.3.4/lib/native/libhadoop.so.1.0.0
    zlib:    true /lib64/libz.so.1
    zstd  :  false
    bzip2:   true /lib64/libbz2.so.1
    openssl: true /lib64/libcrypto.so
    ISA-L:   false libhadoop was built without ISA-L support
    PMDK:    false The native code was built without PMDK support.
    2023-02-18 16:58:39,764 INFO util.ExitUtil: Exiting with status 1: ExitException

可以看到上方还有很多`false`的，不过这不影响hadoop的使用。 如果要解决的话，可以安装这些依赖，然后重新编译hadoop。
