前面我们搭建了hadoop集群，spark集群，也利用容器构建了spark的编程环境。但是一般来说，就并行计算程序的开发，一刚开始一般是在单机上的，比如hadoop的single node。但是老师弄个容器或虚拟机用vscode远程访问式开发，终究还是有些不爽。还好，hadoop和spark都是支持windows的。不妨，我们弄个windows下的开发环境。
然而，windows下开发环境的构建，需要一个转换程序winutils.exe，这个需要根据下载的hadoop的版本对应编译。而且，编译好的exe文件在网上并不好找，一些大虾们编译完了，往往挂在csdn上还要收点费……。所以，还是自己编译吧，好歹还能学点东西。
一、预备环境构建
很多网上的攻略仅仅提到了需要安装些什么软件，但并没有提及为什么。所以，我在安装的时候，本着剃刀原则，尽量少装，然后摔一个坑多装一个。所以，也基本搞清了这些工具的作用——实际上就是，maven集成了一堆的跨平台编译器，并通过插件来调用它们。如果调用的时候找不到，自然就会报错。
所欲i，这里提到的软件，有一个算一个，都得装。
1. CMAKE
到官方网站Download | CMake下载安装包进行安装：
如果不打算手工修改环境变量的话，记得勾上这个：
成功安装，则可在命令行执行版本检查：
Microsoft Windows [版本 10.0.19044.1288]
(c) Microsoft Corporation。保留所有权利。
C:\Users\pig>cmake -version
cmake version 3.26.4
CMake suite maintained and supported by Kitware (kitware.com/cmake).
C:\Users\pig>
2. JDK 1.8
不论是maven的配置文件，还是hadoop的pom文件，默认的java版本都是JDK 1.8。虽然我们之前落过1.8的坑，换成了11，但这里还是改回来的好。否则，不知哪个犄角旮旯的1.8没有改成11，都有可能造成编译失败。
下载后安装：
安装成功后，应该能够在cmd中查看版本号：
Microsoft Windows [版本 10.0.19044.1288]
(c) Microsoft Corporation。保留所有权利。
C:\Users\pig>java -version
java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)
C:\Users\pig>然后在高级系统设置中设置环境变量JAVA_HOME，指向刚才的安装目录。这里我们的安装目录更改过，默认应该在program files目录下面。
3. Maven
在Maven的官方网站Maven – Download Apache Maven下载编译好的binary zip版本，直接解压到windows里。
（1）设置环境变量
maven有2个环境变量需要设置，一个是PATH，一个是MAVEN_HOME
MAVEN_HOME需要设置为我们释放它的目录：
PATH则是需要将maven目录下的bin的绝对目录添加进去：
设置完成后，重启一个cmd，输入mvn -v命令，应该能看到如下结果：
C:\Users\pig>mvn -v
Apache Maven 3.9.2 (c9616018c7a021c1c39be70fb2843d6f5f9b8a1c)
Maven home: C:\maven
Java version: 1.8.0_202, vendor: Oracle Corporation, runtime: C:\Java\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
C:\Users\pig>（2）设置本地仓库及阿里镜像
在MAVEN_HOME/conf目录下的settings.xml文件中，如下设置：
本地仓库目录为c:/m2repo，对应新建这个目录。默认这个目录应该在当前用户目录下的.m2目录中，方便起见，改一下。
<!-- localRepository
| The path to the local repository maven will use to store artifacts.
|
| Default: ${user.home}/.m2/repository
<localRepository>/path/to/local/repo</localRepository>
-->
<localRepository>c:/m2repo</localRepository>添加阿里镜像，这样下载能够快不少：
<mirrors>
<!-- mirror
| Specifies a repository mirror site to use instead of a given repository. The repository that
| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
|
<mirror>
<id>mirrorId</id>
<mirrorOf>repositoryId</mirrorOf>
<name>Human Readable Name for this Mirror.</name>
<url>http://my.repository.com/repo/path</url>
</mirror>
-->
<mirror>
<id>aliyunmaven</id>
<mirrorOf>*</mirrorOf>
<name>阿里云公共仓库</name>
<url>https://maven.aliyun.com/repository/public</url>
</mirror>
<mirror>
<id>maven-default-http-blocker</id>
<mirrorOf>external:http:*</mirrorOf>
<name>Pseudo repository to mirror external repositories initially using HTTP.</name>
<url>http://0.0.0.0/</url>
<blocked>true</blocked>
</mirror>
</mirrors>配置好后，新开cmd窗口，执行 mvn help:system命令

[WARNING]顺利的话，mvn会下载一些默认的依赖项，此时指定的本地库目录下应该就不为空了：
4. 安装Visual Studio
如果安装这个大家伙的唯一目的是编译protobuf获得protoc.exe文件。如果你决定下载已编译好的可执行文件用的话（也就是不编译protobuf），完全可以选择避开这玩意。如果要编译，那就装2010以上的版本。最好2010，因为上到2019，还会出现一些别的问题。
然而，如果还打算继续编译hadoop，并且不希望看到诸如“ Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.3.1:exec”这样的错误的话，VS还是得装的，毕竟maven可能会通过exec插件来调用vs的编译器来进行编译。
5. 安装Git
安装git，除了可能会用到git clone或者git submodule update以外，最主要的作用，是使用Git中自带的git bash。因为后面在编译的时候，maven会使用ant插件运行sh脚本，这个需要bash支持。
下载的官网地址在Git - Downloading Package (git-scm.com) 
一路默认安装就好，但是默认条件下，加入环境变量PATH的是git-cmd目录，bash并不在这个目录中，
这也是我最后编译成功的时候的PATH环境变量情况。可以忽略上面那个ant，保险起见我也手工下载安装了一个，但是感觉没啥作用。maven的antrun插件应该取代它的作用了。
二、编译protobuf
之所以编译protobuf，是因为hadoop编译中需要protoc.exe这个编译工具。所以如果不想麻烦的话，直接去下载编译好的exe文件也行：https://github.com/protocolbuffers/protobuf/releases/download/v2.5.0/protoc-2.5.0-win32.zip。
但是不管是编译源码还是直接下载可执行文件，都一定要认准2.5.0版本——因为hadoop目前的源码编译中要求，不是该版本会造成各种莫名奇妙的插件执行错误。切记切记！！！
1. 下载protobuf
protobuf的下载地址在github上：Release Protocol Buffers v2.5.0 · protocolbuffers/protobuf · GitHub
因为魔法的缘故，打开这个网站需要碰运气，多刷几次就行：
两个红圈中的都是源代码，看起来连接不一样，实际下下来的压缩包完全一样。如果是要下可执行文件，中间那个就是，对应上面我们已经给出的链接。
2. 编译生成protoc
2. 2.5.0版本的protobuf编译起来十分简单，因为它提供了visual studio的工程文件sln，在protobuf\vsprojects目录下，使用VS Studio将其打开即可： 
使用Visual Studio编译的过程就不赘述了，点几个按钮而已。 当然，如果使用的是VS 2019，需要注意以下这个问题：
在默认启动项libprotobuf的header文件加中，找到config.h文件，在其中添加一个宏定义
#define _SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS以避免因为版本问题出现hash_map错误
并且，为了代码能够运行得快点，应该打开各项目的属性面板，选择release 和win32版本：
另外 ，为了避免编译顺序引起的不知名错误，建议一个一个项目的单独编译，不要一上来就直接编译整个工程。总之我这么干冒出来好几百个错误，如果一个一个来，就很顺利通过了。
3. latest protobuf
虽然用不着，但既然我之前掉坑里了（直接选用了23版本的最新protobuf），这里还是说几句。最新版的protobuf没有提供vsprojects目录和sln文件，需要通过命令行生成；当然也可以使用Ninja进行编译。所有这些的详细细节，都在protobuf\cmake\目录下的Readme.rd文件中。
（1）安装git，并使用git更新子模块
其实这一步基本用不上，想用也不好用，所以我就没有把它写在预备条件章节。
官方的说明是，如果我们是使用git clone获得的源码，则需要在protobuf目录下执行更新命令更新子模块，如果是直接下载的zip包或者tar包则不需要。虽然下一步也确实遭遇子模块不齐整的问题，但可以通过直接下载方法解决，这里就不赘述。
C:\protobuf> git submodule update --init --recursive（2）生成Visual Sutdio工程文件
根据官方的说明，需要在有CMakeList.txt文件的目录下执行cmake（也就是根目录下）：
PS F:\build\protobuf232> cmake -G "Visual Studio 16 2019" -A Win32 -B ./build -DCMAKE_INSTALL_PREFIX=./build/output -DCMAKE_CXX_STANDARD=17
CMake Warning:

CMake Error at third_party/utf8_range/CMakeLists.txt:31 (add_subdirectory):

F:/build/protobuf232/third_party/abseil-cpp
does not contain a CMakeLists.txt file.
-- Configuring incomplete, errors occurred!然而，执行结果是缺少abseil-cpp第三方文件——提示中对应的那个目录是空的。并且，cmake会提示说要不要通过git submodule update来更新这个第三方插件……因为有魔法的缘故，这件事是比较玄幻的……我曾经git clone成功下载protobuf23.2，也曾经通过git update成功下载abseil-cpp；但重现这一过程的时候，这两样都无论如何不行了，即使用魔法对抗魔法也没有作用。
PS：
如果还提示说googletest不齐整，不要犹豫，直接使用protobuf_BUILD_TESTS=OFF干掉之：
PS F:\build\protobuf232> cmake -G "Visual Studio 16 2019" -A Win32 -B ./build -DCMAKE_INSTALL_PREFIX=./build/output -DCMAKE_CXX_STANDARD=17 -Dprotobuf_BUILD_TESTS=OFF下载并补齐abseil-cpp
好在这个文件夹是可以在GitHub - abseil/abseil-cpp: Abseil Common Libraries (C++)上下载的：
对应拷贝进去就行了： 
再次执行：
PS F:\build\protobuf232> cmake -G "Visual Studio 16 2019" -A Win32 -B ./build -DCMAKE_INSTALL_PREFIX=./build/output -DCMAKE_CXX_STANDARD=17

PS F:\build\protobuf232>Visual Studio 2019可以用的工程就已经生成了。
（3）编译
VS2019打开，直接在ALL BUILD上右键生成——请忽略我这个灰色，因为我已经点下去了……
一阵有惊无险的warning后，好在是成功生成了：
找到debug底下，这个protoc已经生成了，执行看看版本：
PS F:\build\protobuf232\build\Debug> ./protoc --version
libprotoc 23.2（4）其它方法
我第一次成功生成并没有参考官方的方法，而是自己一阵误打误撞进去的cmake+nmake方法。不同之处在于使用cmake生成的nmake文件，而不是sln：
cmake -G “NMake Makefiles” -DCMAKE_BUILD_TYPE=Debug -Dprotobuf_BUILD_TESTS=OFF然后在对其nmake && nmake install就行了。具体可参考protobuf windows编译和安装_wx637304bacd051的技术博客_51CTO博客
（5）继续生成java版本的protobuf
还是以protobuf 23.2版为例（2.5.0版本一样，莫名其妙的问题还少些）。按照官方的说明，将刚生成的protoc.exe文件拷贝到protobuf所在目录的src子目录下。并且在环境变量PATH中设置这个位置，以确保执行时使用的是这个版本。
网上也有说拷贝到system32下面的。这和windows中cmd寻找命令对应可执行文件的优先序有关，一般来说是先找系统目录，再找环境变量PATH下面，再本级目录（映像如此，准确与否不保证，试试便知）。既然官方说拷贝到src下，应该这个就可以。保险起见，我才加了path。
然后到java目录下，执行mvn test
F:\build\protobuf232\java>mvn test

检查本地库，antrun-plugin好好的在那里，那就不是插件的问题

好在只是在测试代码中，直接把测试代码的编译忽略掉好了。

（6）PS：安装 protobuf 2.5.0
同样，在我们编译hadoop之前，需要按照官方要求，将protobuf 2.5.0给编译了，并且install到本地仓库中去。过程嘛，和上面23.2版本的编译是一样的。这里以直接下载protoc.exe 2.5.0版本的为例。
同样，在protobuf的根目录、src子目录中放入protoc.exe（当然必须和protobuf源代码版本一致，2.5.0版的），然后设好路径，新启动cmd，查看如下：
Microsoft Windows [版本 10.0.19044.1288]
(c) Microsoft Corporation。保留所有权利。
C:\Users\pig>protoc --version
libprotoc 2.5.0
C:\Users\pig>然后到protobuf的java目录 下，直接mvn install：
Microsoft Windows [版本 10.0.19044.1288]
(c) Microsoft Corporation。保留所有权利。
C:\Users\pig>cd c:\protobuf
c:\protobuf>cd java
c:\protobuf\java>mvn install -Dmaven.test.skip=true然后一把过：
（7）其它方法
其实不止使用Visual Studio和maven可以编译protobuf。作为跨平台软件，protobuf还支持其它好多种编译方式，这些编译方式都在对应子目录的Readme.MD中详细记载。
比如参考https://github.com/protocolbuffers/protobuf/blob/main/src/README.md ，可以使用bazel在centos7上进行编译：
首先安装bazel：
dnf install dnf-plugins-core
[root@pighost abseil-cpp]# yum install dnf-plugins-core -y

启用模块流:
javapackages-runtime 201801 然后编译，在protobuf的根目录下执行：
bazel build :protoc :protobuf
生成结果位于bazel-bin目录下。
三、编译Hadoop
完成protobuf 2.5.0的install后，就可以开始编译hadoop了。
1. 下载Hadoop源码
直接到官方下载源码包，解压到需要的目录下面就行 
我是在c盘下建立了一个hadoop目录，然后把源代码解压进去了。需要注意的是，最后那个hadoop-yarn-project的子目录很深，所以要尽可能把代码解压到靠近根目录的位置。否则，在我正版的win11家庭版上，会因为目录长度限制而无法解压（其实似乎无论如何都规避不了，不过好在我们最后并不需要这个子目录里面的东西，所以直接无视了）；而在我下载的未激活版本的windows专业版上，这个问题不存在。 
2. 直接编译
c:\hadoop>mvn package -Dmaven.test.skip=true
[INFO] Scanning for projects...（1）没有安装VS2019导致的错误
直接上手package，一阵子以后，收到以下错误：
[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.3.1:exec (convert-ms-winutils) on project hadoop-common: Command execution failed.: Process exited with an error: 1 (Exit value: 1) -> [Help 1]

[ERROR]
[ERROR] After correcting the problems, you can resume the build with the command
[ERROR] mvn <args> -rf :hadoop-common每次收到这个错误都是崩溃的。因为引起它的原因千奇百怪。这次的原因，是因为在虚拟机里面，我偷懒没有安装Visual Studio，导致无法编译winutils。
所以下载并安装——本来是为了避免在虚拟机中如此痛苦——结果也没避开。
使用Visual Studio的命令行工具进去重新mvn pakcage，这次成功过了winutils这一关，并且顺利生成了WinUtils.exe。其实我们需要的仅此而已。
（2）没有安装git-bash导致的错误
不过接着往下，我们又遇到了新的错误：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (common-test-bats-driver) on project hadoop-common: An Ant BuildException has occured: Execute failed: java.io.IOException: Cannot run program "bash" (in directory "C:\hadoop\hadoop-common-project\hadoop-common\src\test\scripts"): CreateProcess error=2, 系统找不到指定的文件。

[ERROR] mvn <args> -rf :hadoop-common这个错误出现的原因，是因为没有安装git-bash，看ERROR报出的信息，实际就是maven使用antrun插件试图去执行build-main.xml文档（实际使用bash调用对应的sh脚本）时，无法找到bash文件。
所以，记得安装git-bash，并且正确的设置PATH，使编译器能够找到git/bin/bash。
（3）跳过不太重要的部分
接着往下，马上又碰到新的错误：

win10编译hadoop3.2.1_windows编译hadoop_冰上浮云的博客-CSDN博客。当然，最简单的绕过方法，是直接从下一个包开始编译：
mvn package -Dmaven.test.skip=true -rf :hadoop-hdfs-nfs
只要这个native-client不影响咱们啥就好；具体啥原因这里就不深究了。
不过不知道是不是我们skip了test的原因……因为在上一次成功编译时，我使用的mvn test，没有遇到过类似问题。
（4）编译到中途，缺少denpendcy，或者pom路径不对
先多说一句，如果遇上duplicate jar库，需要在mvn命令中添加clean参数。当然，这有可能把（3）中我们手工构建的目录删掉，没关系，碰到（3）错误的时候重新构建并去掉clean参数继续执行就行了。
最终是需要mvn install package一起上的。
然后在即将大功告成的某步，居然被告知ensure-jars-have-correct-contents.sh找不到文件：

（7）还不算完
虽然编译成功了，我们还是只能得到一大堆的jar，也就是说，如果需求是改造hadoop代码，替换原来的jar包，那么到这一步可以结束了。但是如果需求是得到我们自己的hadoop安装包，还需要本地重新编译一下：
使用本地编译命令：
mvn package -Pdist -DskipTests -Dtar -Dmaven.javadoc.skip=true
或者
mvn package -Pdist，native-win -DskipTests -Dtar -Dmaven.javadoc.skip=true从Maven Embedder - Maven CLI Options Reference (apache.org) 语焉不详的说明来看，我认为是-Pdist 和-Dtar起的作用。也就是说生成分发包和tar包（估计是根据不同的编译平台生成不同的结果）……不深究了，总之管用就行。
这一轮编译完成后，才算是能看到可部署的Hadoop文件，在C:\hadoop\hadoop-dist\target\hadoop-3.3.5下：
弄完以后发现一篇写得比较详尽的文章，参考价值较高：Compile and Build Hadoop 3.2.1 on Windows 10 Guide (kontext.tech)
四、Hadoop + Spark
当然，如果你不太相信自己编译的这个Hadoop，完全可以官网上下一个已经编译好的，至少Spark我们就打算这么干了。
把从官网下载的binary版本的压缩包解压到主机上： 
（1）设置环境变量
设置好环境变量。对于hadoop和spark来说，需要JAVA_HOME、HADOOP_HOME、SPARK_HOME3个环境变量，还需要配置PATH环境变量以便调用hdfs、spark-shell之类的命令。
设置前改个名字，避免出现空格横线之类特别的字符。
在PATH变量中，主要加入HADOOP和SPARK的bin目录位置，因为我们要调用的命令都在这里，sbin里面主要是用于管理集群的工具，所以无所谓。
（2）运行看看
设置好后，直接运行该spark-shell可以发现，一个是前面会提示缺失winutils.exe，后面也不能“很干净”的退出。
当然，如果只做交互式分析，而且没有强迫症的话，这也没啥。
但是，如果是编程， 如下的这一句执行下来，你会发现目录下仅仅多了一个空的result目录，里面没有任何结果。这就是因为本应由winutils提供的接口不存在所导致的。
（3）拷贝winutils
解决办法也很简单，直接把我们刚才编译产生的winutils拷贝到hadoop的bin目录下即可。生成的文件在\hadoop\hadoop-common-project\hadoop-common\target\bin下面：
然后重新开启一个cmd执行spark-shell：
可以看到winutils的问题已经解决了。
统计结果也顺利生成。文章来源：https://www.toymoban.com/news/detail-484249.html
五、搭建hadoop + Spark + VSCODE
写了一整天，实在写不动了。VSCODE的搭建没有什么幺蛾子了，和前面几篇讲的方法一样，不赘述。文章来源地址https://www.toymoban.com/news/detail-484249.html
到了这里，关于CENTOS上的网络安全工具（二十四）Windows下的Hadoop+Spark编程环境构建的文章就介绍完了。如果您还想了解更多内容，请在右上角搜索TOY模板网以前的文章或继续浏览下面的相关文章，希望大家以后多多支持TOY模板网！
