准备工作

下载 Hadoop 源码 Source (当前最新 2.9.2)

https://hadoop.apache.org/releases.html

打开压缩包会看到 BUILDING.txt 文件，这是官方提供的编译说明，参看 Linux 部分

Requirements:

* Unix System

* JDK 1.7 or 1.8

* Maven 3.0 or later

* Findbugs 1.3.9 (if running findbugs)

* ProtocolBuffer 2.5.0

* CMake 2.6 or newer (if compiling native code), must be 3.0 or newer on Mac

* Zlib devel (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)

* Internet connection for first build (to fetch all Maven and Hadoop dependencies)

* python (for releasedocs)

* Node.js / bower / Ember-cli (for YARN UI v2 building)

官方编译参数说明

Maven build goals:

 * Clean                     : mvn clean [-Preleasedocs]

 * Compile                   : mvn compile [-Pnative]

 * Run tests                 : mvn test [-Pnative]

 * Create JAR                : mvn package

 * Run findbugs              : mvn compile findbugs:findbugs

 * Run checkstyle            : mvn compile checkstyle:checkstyle

 * Install JAR in M2 cache   : mvn install

 * Deploy JAR to Maven repo  : mvn deploy

 * Run clover                : mvn test -Pclover [-DcloverLicenseLocation=${user.name}/.clover.license]

 * Run Rat                   : mvn apache-rat:check

 * Build javadocs            : mvn javadoc:javadoc

 * Build distribution        : mvn package [-Pdist][-Pdocs][-Psrc][-Pnative][-Dtar][-Preleasedocs][-Pyarn-ui]

 * Change Hadoop version     : mvn versions:set -DnewVersion=NEWVERSION

 Build options:

  * Use -Pnative to compile/bundle native code

  * Use -Pdocs to generate & bundle the documentation in the distribution (using -Pdist)

  * Use -Psrc to create a project source TAR.GZ

  * Use -Dtar to create a TAR with the distribution (using -Pdist)

  * Use -Preleasedocs to include the changelog and release docs (requires Internet connectivity)

  * Use -Pyarn-ui to build YARN UI v2. (Requires Internet connectivity)

 Snappy build options:

   Snappy is a compression library that can be utilized by the native code.

   It is currently an optional component, meaning that Hadoop can be built with

   or without this dependency.

  * Use -Drequire.snappy to fail the build if libsnappy.so is not found.

    If this option is not specified and the snappy library is missing,

    we silently build a version of libhadoop.so that cannot make use of snappy.

    This option is recommended if you plan on making use of snappy and want

    to get more repeatable builds.

  * Use -Dsnappy.prefix to specify a nonstandard location for the libsnappy

    header files and library files. You do not need this option if you have

    installed snappy using a package manager.

  * Use -Dsnappy.lib to specify a nonstandard location for the libsnappy library

    files.  Similarly to snappy.prefix, you do not need this option if you have

    installed snappy using a package manager.

  * Use -Dbundle.snappy to copy the contents of the snappy.lib directory into

    the final tar file. This option requires that -Dsnappy.lib is also given,

    and it ignores the -Dsnappy.prefix option. If -Dsnappy.lib isn't given, the

    bundling and building will fail.

 OpenSSL build options:

   OpenSSL includes a crypto library that can be utilized by the native code.

   It is currently an optional component, meaning that Hadoop can be built with

   or without this dependency.

  * Use -Drequire.openssl to fail the build if libcrypto.so is not found.

    If this option is not specified and the openssl library is missing,

    we silently build a version of libhadoop.so that cannot make use of

    openssl. This option is recommended if you plan on making use of openssl

    and want to get more repeatable builds.

  * Use -Dopenssl.prefix to specify a nonstandard location for the libcrypto

    header files and library files. You do not need this option if you have

    installed openssl using a package manager.

  * Use -Dopenssl.lib to specify a nonstandard location for the libcrypto library

    files. Similarly to openssl.prefix, you do not need this option if you have

    installed openssl using a package manager.

  * Use -Dbundle.openssl to copy the contents of the openssl.lib directory into

    the final tar file. This option requires that -Dopenssl.lib is also given,

    and it ignores the -Dopenssl.prefix option. If -Dopenssl.lib isn't given, the

    bundling and building will fail.

   Tests options:

  * Use -DskipTests to skip tests when running the following Maven goals:

    'package',  'install', 'deploy' or 'verify'

  * -Dtest=<TESTCLASSNAME>,<TESTCLASSNAME#METHODNAME>,....

  * -Dtest.exclude=<TESTCLASSNAME>

  * -Dtest.exclude.pattern=**/<TESTCLASSNAME1>.java,**/<TESTCLASSNAME2>.java

  * To run all native unit tests, use: mvn test -Pnative -Dtest=allNative

  * To run a specific native unit test, use: mvn test -Pnative -Dtest=<test>

  For example, to run test_bulk_crc32, you would use:

  mvn test -Pnative -Dtest=test_bulk_crc32

编译

# 解压 hadoop 源码

tar -zxf /opt/bak/hadoop-2.9.-src.tar.gz -C /opt/app/

# 编译

cd /opt/app/hadoop-2.9.-src/

mvn clean package -Pdist,native -DskipTests –Dtar

# 带 snappy 版本编译

mvn clean package -Pdist,native -DskipTests -Dtar -Dbundle.snappy -Dsnappy.lib=/usr/local/lib64

# -Pdist,native　　　　　　　　　　：把重新编译生成的hadoop动态库

# -DskipTests　　　　　　　　　　　：跳过测试

# -Dtar　　　　　　　　　　　　　　 ：最后把文件以tar打包

# -Dbundle.snappy　　　　　　　　 ：添加snappy压缩支持(默认官网下载的是不支持的)

# -Dsnappy.lib=/usr/local/lib　 ：指snappy在编译机器上安装后的库路径

snappy 压缩支持，可以在安装 Hadoop 后用命令检查，在 lib/native 路径下也有相关文件

hadoop checknative

编译过程中请保持网络畅通，编译可能会因为包依赖下载出错而失败，可多试几次。
