1 - 為什麼要自己編譯 Hadoop
一般個人安裝使用的都是 Apache 的 Hadoop（還有 CDH Hadoop等等）。
從 Apache 官網下載的安裝包是在一些特定的機器上編譯而來的，並不能相容所有的環境，尤其是本地庫（用來壓縮，支援C程式等等），不同平臺有不同的限制。
2 - 準備編譯環境
1）本機系統：macOS Big Sur 11.0.1版本；
保證能夠連線網際網路，Linux 系統，需要關閉防火牆和SELinux：
service iptables stop
chkconfig iptables off
# 關閉SELinux
vim /etc/selinux/config
# 註釋：SELINUX=enforcing
# 新增：SELINUX=disable
2）配置 JDK 環境變數，版本為1.8.0_162；
Linux 系統，一般要解除安裝掉系統自帶的 Java 環境：
# 檢視已安裝的版本：
rpm -qa | grep java
# 解除安裝：
rpm -e java-1.6.0-openjdk-1.6.0.41-1.13.13.1.el6_8.x86_64 java-1.7.0-openjdk-1.7.0.131-2.6.9.0.el6_8.x86_64
3）安裝 Maven，版本為 3.5.2；
為了加速依賴的下載，可以新增阿里雲的 Maven 映象：
<mirror>
<id>alimaven</id>
<name>aliyun maven repo</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
4）上述軟體的環境變數資訊：
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_162.jdk/Contents/Home
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.
export PATH=$JAVA_HOME/bin:$PATH:.
export MAVEN_HOME=/usr/local/apache-maven-3.5.2
export PATH=$PATH:$MAVEN_HOME/bin
export HADOOP_HOME=/Users/healchow/bigdata/hadoop-3.2.1
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
3 - 安裝依賴庫
macOS 系統一般通過 Homebrew 安裝依賴，方便快捷。
建議把 Homebrew 的倉庫修改到國內，避免速度慢導致安裝失敗：https://zhuanlan.zhihu.com/p/351199589。
1）安裝 gcc，cmake，以及 GNU 相關庫：
brew install gcc cmake autoconf automake libtool
2）安裝 gzip、bzip2、zlib、snappy 等壓縮庫：
brew install gzip bzip2 zlib
手動安裝 snappy 1.1.4 —— 其他版本會出錯！
# 下載並解壓：
wget https://github.com/google/snappy/archive/1.1.4.tar.gz
tar -zxf 1.1.4.tar.gz
cd snappy-1.1.4
# 指定安裝路徑，便於 brew 連結（不指定，就會安裝到 /usr/local/bin）
./autogen.sh
./configure --prefix=/usr/local/Cellar/snappy/1.1.4
# 編譯並安裝到上面的路徑：
make && make install
# 新增到環境變數：
brew link snappy
3）安裝 openssl 依賴，並配置環境變數：
brew install openssl
向 ~/.bash_profile 中新增環境變數：
export OPENSSL_ROOT_DIR="/usr/local/opt/openssl@1.1"
export OPENSSL_INCLUDE_DIR="$OPENSSL_ROOT_DIR/include"
export PKG_CONFIG_PATH="${OPENSSL_ROOT_DIR}/lib/pkgconfig"
# 儲存後，令環境變數立即生效：
source ~/.bash_profile
4）手動安裝 protobuf 2.5.0：
必須安裝此版本，否則在編譯原始碼過程中，會報錯：
org.apache.maven.plugin.MojoExecutionException: protoc version is ‘libprotoc 3.11.2’, expected version is ‘2.5.0’
brew 源中是最新版，沒有 2.5.0，需要下載然後編譯安裝。
下載連結：https://github.com/protocolbuffers/protobuf/releases/tag/v2.5.0，解壓後，編譯安裝：
wget https://github.com/google/protobuf/releases/download/v2.5.0/protobuf-2.5.0.tar.gz
tar -zxf protobuf-2.5.0.tar.gz
cd protobuf-2.5.0
# 指定安裝路徑，便於 brew 連結（不指定，就會安裝到 /usr/local/bin）
./configure --prefix=/usr/local/Cellar/protobuf/2.5.0
# 編譯，並安裝到上面的路徑：
make && make install
# 新增到環境變數：
brew link protobuf
5）可選安裝 isa-l：
先安裝 nasm：brew install nasm
然後下載原始碼包（https://github.com/intel/isa-l/releases），編譯安裝：
cd isa-l-2.28.0
# 執行建立configure
autoreconf --install --symlink -f
./configure --prefix=/usr/local/Cellar/isa-l --libdir=/usr/local/Cellar/isa-l/lib AS=yasm --target=darwin
# 編譯安裝：
make && make install
# 建立軟連結：
cd /usr/local/lib
ln -s /usr/local/Cellar/isa-l/lib/libisal.2.dylib libisal.2.dylib
ln -s /usr/local/Cellar/isa-l/lib/libisal.a libisal.a
ln -s /usr/local/Cellar/isa-l/lib/libisal.dylib libisal.dylib
ln -s /usr/local/Cellar/isa-l/lib/libisal.la libisal.la
cd /usr/local/lib/pkgconfig
ln -s /usr/local/Cellar/isa-l/lib/pkgconfig/libisal.pc libisal.pc
4 - 編譯 Hadoop 原始碼
下載 Apache Hadoop 原始碼包，這裡下載 3.2.1 版本（https://archive.apache.org/dist/hadoop/core/hadoop-3.2.1/）；
下載後，解壓到 ${HOME}/bigdata/。
編譯原始碼，編譯命令是：
cd ${HOME}/bigdata/hadoop-3.2.1-src
# 編譯支援 snappy 壓縮，需要指定 openssl.prefix，否則預設使用 macOS 自帶的 openssl，會導致編譯失敗：
# -e -X 引數是列印編譯過程中的所有日誌：
mvn clean package -DskipTests -Pdist,native -Dmaven.javadoc.skip -Dtar \
-Drequire.bzip2 -Dbzip2.prefix=/usr/local/Cellar/bzip2/1.0.8 \
-Drequire.openssl -Dopenssl.prefix=/usr/local/Cellar/openssl@1.1/1.1.1k \
-Drequire.snappy -Dsnappy.lib=/usr/local/Cellar/snappy/1.1.4/lib \
-Drequire.isal -Disal.prefix=/usr/local/Cellar/isa-l -Disal.lib=/usr/local/Cellar/isa-l/lib \
-e -X
5 - 遇到的問題及解決方法
5.1 hadoop-common 模組編譯出錯
[WARNING] CMake Warning (dev) at CMakeLists.txt:47 (find_package):
[WARNING] Policy CMP0074 is not set: find_package uses <PackageName>_ROOT variables.
[WARNING] Run "cmake --help-policy CMP0074" for policy details. Use the cmake_policy
[WARNING] command to set the policy and suppress this warning.
[WARNING]
[WARNING] Environment variable ZLIB_ROOT is set to:
[WARNING]
[WARNING] /usr/local/Cellar/zlib/1.2.11/
[WARNING]
[WARNING] For compatibility, CMake is ignoring the variable.
[WARNING] This warning is for project developers. Use -Wno-dev to suppress it.
[WARNING]
[WARNING] CMake Error at /usr/local/Cellar/cmake/3.20.5/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
[WARNING] Could NOT find ZLIB (missing: ZLIB_LIBRARY) (found version "1.2.11")
[WARNING] Call Stack (most recent call first):
[WARNING] /usr/local/Cellar/cmake/3.20.5/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:594 (_FPHSA_FAILURE_MESSAGE)
[WARNING] /usr/local/Cellar/cmake/3.20.5/share/cmake/Modules/FindZLIB.cmake:120 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
[WARNING] CMakeLists.txt:47 (find_package)
它提示說找不到 ZLIB_LIBRARY，而 ZLIB_ROOT 被忽略了。看看我的環境變數：
export ZLIB_ROOT=/usr/local/Cellar/zlib/1.2.11
export ZLIB_LIBRARY=/usr/local/Cellar/zlib/1.2.11/lib
export ZLIB_INCLUDE_DIR=/usr/local/Cellar/zlib/1.2.11/include
經過一番查詢，原來 XXX_ROOT 在 CMake 3.12 以上是這樣的作用：
再參考這位大神（https://github.com/MarkDana/Compile-Hadoop2.2.0-on-MacOS）的分析：
如果是通過
brew安裝的zlib庫，那麼可以到這個路徑檢視：
cd /usr/local/Cellar/cmake/3.20.5/share/cmake/Modules
vim FindZLIB.cmake
約 60行，它會先去檢視 ZLIB_ROOT 變數：
所以我們只需要設定 ZLIB_ROOT 即可，為了讓此變數生效，需要在 CMakeFile 中啟用 cmake 的 CMP0074 策略：
修改報錯專案對應的 CMake 配置：
vim hadoop-common-project/hadoop-common/src/CMakeLists.txt，啟用新特性：
# 在 cmake_minimum_required(VERSION 3.1 FATAL_ERROR) 之後，加入這一行：
cmake_policy(SET CMP0074 NEW)
最後，環境變數中只需要保留這一行即可：
export ZLIB_ROOT=/usr/local/Cellar/zlib/1.2.11
然後，此錯誤就消失了。
5.2 hadoop-common 模組，仍然出錯
[WARNING] CMake Warning (dev) in CMakeLists.txt:
[WARNING] No project() command is present. The top-level CMakeLists.txt file must
[WARNING] contain a literal, direct call to the project() command. Add a line of
[WARNING] code such as
[WARNING]
[WARNING] project(ProjectName)
[WARNING]
[WARNING] near the top of the file, but after cmake_minimum_required().
[WARNING]
[WARNING] CMake is pretending there is a "project(Project)" command on the first
[WARNING] line.
[WARNING] This warning is for project developers. Use -Wno-dev to suppress it.
[WARNING]
[WARNING] CMake Error at CMakeLists.txt:68 (message):
[WARNING] Required bzip2 library and/or header files could not be found.
[WARNING]
[WARNING]
[WARNING] -- Configuring incomplete, errors occurred!
找不到 bzip2 庫或相關的標頭檔案。。。可是我的 bzip2 環境變數都已經設定了呀：
export BZIP2_ROOT=/usr/local/Cellar/bzip2/1.0.8
export BZIP2_INCLUDE_DIR=/usr/local/Cellar/bzip2/1.0.8/include
export BZIP2_LIBRARY=/usr/local/Cellar/bzip2/1.0.8
其他各種環境變數和 LDFLAGS、CPPFLAGS 設定都無效；
經過各種搜尋，感覺 macOS 上就不能編譯 bzip2。所以，我改了這裡，跳過檢查：
# 修改下面一行，直接設定了 REQUIRE_BZIP2，即 TRUE
# if(BZIP2_INCLUDE_DIR AND BZIP2_LIBRARIES)
if(REQUIRE_BZIP2)
5.3 MapReduce NativeTask 模組編譯出錯
[WARNING] 2 warnings and 12 errors generated.
[WARNING] make[2]: *** [CMakeFiles/nttest.dir/main/native/test/TestCompressions.cc.o] Error 1
[WARNING] make[2]: *** Waiting for unfinished jobs....
[WARNING] make[1]: *** [CMakeFiles/nttest.dir/all] Error 2
[WARNING] make: *** [all] Error 2
......
[INFO] Apache Hadoop MapReduce NativeTask ................. FAILURE [ 21.506 s]
搜尋後得知，brew 安裝的 snappy 版本是最新的 1.1.9，是通過 C++11 編譯的，但是 Hadoop 3.2.1 的編譯不支援C++11。
期間，又嘗試安裝了 snappy 1.1.5 編譯還是會出錯：
[WARNING] CMake Error at CMakeLists.txt:96 (message):
[WARNING] Required snappy library could not be found.
[WARNING] SNAPPY_LIBRARY=SNAPPY_LIBRARY-NOTFOUND, SNAPPY_INCLUDE_DIR=,
[WARNING] CUSTOM_SNAPPY_INCLUDE_DIR=, CUSTOM_SNAPPY_PREFIX=, CUSTOM_SNAPPY_INCLUDE=
嘗試新增了環境變數，不起作用：
export SNAPPY_LIBRARY=/usr/local/Cellar/snappy/1.1.5
export SNAPPY_INCLUDE_DIR=/usr/local/Cellar/snappy/1.1.5/include
# 仍然會報下面的錯：
Required snappy library could not be found.
[WARNING] SNAPPY_LIBRARY=SNAPPY_LIBRARY-NOTFOUND, SNAPPY_INCLUDE_DIR=,
[WARNING] CUSTOM_SNAPPY_INCLUDE_DIR=, CUSTOM_SNAPPY_PREFIX=, CUSTOM_SNAPPY_INCLUDE=
找了這麼一個編譯 snappy 的方法，macOS Big Sur 系統驗證不可用：
下載 https://github.com/electrum/hadoop-snappy.git，並編譯，然後拷貝至 Hadoop 叢集的 native 下。
這裡還有一個大神解決 snappy 版本編譯的操作，我沒有試，提供參考：https://blog.csdn.net/weixin_44570264/article/details/106846117
所以我又安裝了最上面提到的 snappy 1.1.4，再測試，然後它終於編譯成功了✌️
6 - 編譯成功，測試驗證
編譯命令已經放在上面第4姐了。貼上編譯成功的證明✌️

看截圖：
編譯好的安裝檔案，在這個目錄下：
我們需要的壓縮包在 lib/native 下。
${原始碼}/hadoop-dist/target/hadoop-3.2.1
# 本地庫包在這裡：
${原始碼}/hadoop-dist/target/hadoop-3.2.1/lib/native
拷貝 native 下的檔案，到已經 Hadoop 叢集的安裝目錄中，然後檢查它對本地庫的支援：
沒有惱人的 WARN 警告了，zlib、snappy 等壓縮功能也都有了✌️
7 - 經驗總結
1）儘量用 CentOS系統編譯。macOS 編譯，大部分本地庫都不會通過，會卡死在 CMake。
2）額外使用的環境變數如下：
# 本地編譯 Hadoop，必須設定 ZLIB_ROOT，且在 CMakeFile 中啟用 cmake 的 CMP0074 策略：
export ZLIB_ROOT=/usr/local/Cellar/zlib/1.2.11
# export ZLIB_LIBRARY=/usr/local/Cellar/zlib/1.2.11/lib
# export ZLIB_INCLUDE_DIR=/usr/local/Cellar/zlib/1.2.11/include
export OPENSSL_ROOT_DIR="/usr/local/opt/openssl@1.1"
export OPENSSL_INCLUDE_DIR="$OPENSSL_ROOT_DIR/include"
export PKG_CONFIG_PATH="${OPENSSL_ROOT_DIR}/lib/pkgconfig"
