hadoop-2.6.0-cdh5.7.0源码编译支持压缩

在hadoop-2.6.0-cdh5.7.0源码中有个BUILDING.txt文件，里面列出了编译所需依赖组件。

Requirements:

Unix System
JDK 1.7+
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 )
Internet connection for first build (to fetch all Maven and Hadoop dependencies)

转载链接文章中或通过yum安装或通过自己下载提供了所有正确版本组件，并将已下载组件通过百度云分享。我想补充一点的是，yum安装可能报出Another app is currently holding the yum lock; waiting for it to exit…的错误，可参考https://blog.csdn.net/testcs_…强制关闭yum进程来解决。
根据BUILDING.txt提示

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)
Building distributions:
Create binary distribution without native code and withoutdocumentation:
$ mvn package -Pdist -DskipTests -Dtar
Create binary distribution with native code and with documentation:
$ mvn package -Pdist,native,docs -DskipTests -Dtar

使用mvn clean package -Pdist,native -DskipTests -Dtar编译，编译完成后，默认会在源码根目录的hadoop-dist目录下生成target，里面的hadoop-2.6.0-cdh5.7.0文件夹就是已经编译好并已解压的hadoop了（直接用的），可以将其拷贝到自定义的位置进行部署配置。

可以看到编译的hadoop支持了各种压缩，亲测有效！
