背景
周五尝试用hive建表时，出现了问题，需要修改hadoop源码，而后编译。
但是在编译时，遇到了不少问题，周日耗时一天，排查完毕，编译通过

1、Failed to execute goal org.apache.hadoop:hadoop-maven-plugins:3.0.2:protoc (compile-protoc) on project hadoop-common: org.apache.maven.plugin.MojoExecutionException: 'protoc --version' did not return a version
解决方法：安装protobuf2.5-win
1、下载zip压缩包
2、解压压缩包，然后把解压路径添加到环境变量path里
2、 Failed to execute goal org.codehaus.mojo:native-maven-plugin:1.0-alpha-8:javah (default) on project hadoop-common: Error running javah command: Error executing command line. Exit code:1 -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.codehaus.mojo:native-maven-plugin:1.0-alpha-8:javah (default) on project hadoop-common: Error running javah command
javah出现了问题，解决方法：
修改源码目录下hadoop-common-project\hadoop-common\pom.xml文件，把所有的javahPath标签内容改成javah的绝对路径
3、Cannot run program "msbuild" (in directory "D:\hadoop-3.0.2-src\hadoop-common-project\hadoop-common"): CreateProcess error=2, 系统找不到指定的文件。
解决方法：安装VS Code，然后把msbuild可执行文件的绝对路径添加到path里(C:\Program Files (x86)\MSBuild\14.0\Bin)
4、 Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (make) on project hadoop-hdfs-native-client: An Ant BuildException has occured: exec returned: 1
[ERROR] around Ant part ...<exec failοnerrοr="true" dir="D:\hadoop-3.0.2-src\hadoop-hdfs-project\hadoop-hdfs-native-client\target/native" executable="msbuild">... @ 11:135 in D:\hadoop-3.0.2-src\hadoop-hdfs-project\hadoop-hdfs-native-client\target\antrun\build-main.xml
cmake和MsBuild(MSB1009找不到)莫名报错，暂时在hadoop-hdfs-project\hadoop-hdfs-native-client\pom.xml中，屏蔽它们的错误
5、 Could not resolve dependencies for project org.apache.hadoop:hadoop-resourceestimator:jar:3.0.2: Could not transfer artifact org.ojalgo:ojalgo:jar:43.0 from/to nexus-aliyun (http://maven.aliyun.com/nexus/content/groups/public): GET request of: org/ojalgo/ojalgo/43.0/ojalgo-43.0.jar from nexus-aliyun failed: Connection reset
解决方法：把ojalgo-43.0.jar下载下来，复制到本地maven仓库文件夹的org\ojalgo\ojalgo\jar\43.0\目录下
编译结果
