Mac 下编译 Hadoop-2.9.2

系统环境

系统： Mac OS_10.14.4maven： Apache Maven 3.6.0jdk: jdk_1.8.0_201ProtocolBuffer： portoc-2.5.0zlib： 1.2.3-libOpenSSL： 1_0_2rcmale： 3.14.3-win64-x64Cygwin： 2.897_x86_64hadoop： hadoop-2.9.2snappy: 复制代码

搭建编译环境

1.java环境在oracle官网下载安装安装好配置好环境变量2.maven我用的是brew直接安装的`brew install maven`3.cmake 使用brew安装 `brew install cmake`4.openssl 使用brew安装 `brew install openssl`5.snappy 使用brew安装 `brew install snappy`6.zlib 使用brew 安装 `brew install zlib`7.protobuf由于必须使用2.5.0版本需要自行[下载](https://github.com/protocolbuffers/protobuf/releases)安装下载后解压后进入protobuf目录# 配置$ ./configure --prefix=/usr/local/Cellow/protoc/2.5/# 编译$ make# 安装$ make install# 配置环境变量 `~/.bash_profile` 或 `~/.zshrc`export PATH="/usr/local/Cellow/protoc/2.5/bin:$PATH"# 验证protoc版本$ protoc --version复制代码

过程中可能遇到的问题

• 1.[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (make) on project hadoop-pipes: An Ant BuildException has occured: exec returned: 1 [ERROR] around Ant part ...... @ 5:153 in /Users/Downloads/hadoop-2.9.2/hadoop-tools/hadoop-pipes/target/antrun/build-main.xml

解决办法： 由于这个xml中的编译指令中需要用到一个环境变量OPENSSL_ROOT_DIR由于我们前面没有配置所以他在执行的时候就会报错，需要在~/.bash_profile 或 ~/.zshrc中指定OPENSSL_ROOT_DIR的安装目录我的配置是export OPENSSL_ROOT_DIR="/usr/local/Cellor/openssl/1.0.2r"

• 2.由于OpenSSL爆出有重大的漏洞Mac OS没有使用OpenSSL而是使用了LibreSSl可以在你的Mac下执行which openssl 然后找到/usr/bin/openssl 执行/usr/bin/openssl version 就会出现LibreSSl 2.6.4，但是编译hadoop必须要使用openssl，可以吧openssl的引用改一个名称，但是Mac是不允许你关闭Mac的保护模式但是不建议这样做，我们可以修改系统的shell的环境变量使自己配置的环境变量覆盖系统的环境变量，例如：export PATH="/usr/local/Cellor/openssl/1.0.2r/bin:$PATH"

编译hadoop

# 下载[hadoop源码](https://hadoop.apache.org/releases.html)# 解压缩后进入hadoop源码路径# 执行一条maven命令（你的maven需要配置到环境变量中）$ mvn package -Pdist,native -DskipTests -Dtar# 编译过程不会太长，但是下载各种依赖就会浪费很长时间，耐心等待！# 过程中可能会出现各各样的问题我只是列举了我花费比较久时间解决的问题，如果无法解决可以留言。复制代码

编译完成

经过漫长的编译终于出现了令人兴奋的画面
