CentOS7环境下编译Hadoop3.2.1源码

1.环境搭建

镜像版本： CentOS-7-x86_64-DVD-1908.iso

SOFTWARE SELECTION：GNOME Desktop（桌面版，比Minimal Install版多部分软件）

 Hadoop版本：hadoop-3.2.1-src.tar.gz

 下载地址：All previous releases of Hadoop are available from the Apache release archive site.

 hadoop源码编译所需的其他软件在源码包的BUILDING.txt文件中有详细介绍，编译过程中发生错误，99%是因为所需软件未安装，根据错误描述安装对应版本软件即可顺利编译。

Build instructions for Hadoop

----------------------------------------------------------------------------------
Requirements:

* Unix System
* JDK 1.8
* Maven 3.3 or later
* ProtocolBuffer 2.5.0
* 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)

 2.软件安装

 总结：

①不编译native code和documentation

Create binary distribution without native code and without documentation:

  $ mvn package -Pdist -DskipTests -Dtar -Dmaven.javadoc.skip=true

则仅需安装JDK 1.8，Maven 3.3 or later，ProtocolBuffer 2.5.0，gcc，gcc-c++，patch即可

②编译native code和documentation

Create binary distribution with native code and with documentation:

  $ mvn package -Pdist,native,docs -DskipTests -Dtar

除JDK 1.8，Maven 3.3 or later，ProtocolBuffer 2.5.0，gcc，gcc-c++，patch还需要安装CMake 3.1 or newer，zlib-devel，openssl-devel，cyrus-sasl-devel

 1.JDK安装
