环境：
* 类Unix系统
* JDK 1.6 以上
* Maven 3.0 (用于代替ant的编译环境)
* Forrest 0.8 (Apache Forrest是一个平台独立的文档框架。把来自各种不同的输入数据源转换成用一种或多种输出格式(比如HTML,PDF等)来统一显示的发布系统。它基于Apache Cocoon并分离了内容与内容结构,不仅可以生成静态的文档也可以当作一个动态的服务器。如果要生成文档则需要。)
* Findbugs 1.3.9 (Java 语言静态分析工具，用于查找bug。非必须。)
* ProtocolBuffer 2.4.1+ ( MapReduce 和 HDFS 用google protocol buffer来压缩和交换数据)
* Autotools (如果编译 native code需要)
* 第一次编译要用到网络连接 (用于获取所有 Maven 和 Hadoop 依赖库)
安装maven
[zhouhh@h185 ~]$ wget http://labs.mop.com/apache-mirror/maven/maven-3/3.0.4/binaries/apache-maven-3.0.4-bin.tar.gz
[zhouhh@h185 ~]$ vi .bashrc
export PATH=$PATH:/home/zhouhh/maven/bin
maven用法：
* Clean : mvn clean
* Compile : mvn compile [-Pnative]
* Run tests : mvn test [-Pnative]
* Create JAR : mvn package
* Run findbugs : mvn compile findbugs:findbugs
* Run checkstyle : mvn compile checkstyle:checkstyle
* Install JAR in M2 cache : mvn install
* Deploy JAR to Maven repo : mvn deploy
* Run clover : mvn test -Pclover [-DcloverLicenseLocation=${user.name}/.clover.license]
* Run Rat : mvn apache-rat:check
* Build javadocs : mvn javadoc:javadoc
* Build distribution : mvn package [-Pdist][-Pdocs][-Psrc][-Pnative][-Dtar]
* Change Hadoop version : mvn versions:set -DnewVersion=NEWVERSION
Build 选项:
* Use -Pnative to compile/bundle native code
* Use -Dsnappy.prefix=(/usr/local) & -Dbundle.snappy=(false) to compile
Snappy JNI bindings and to bundle Snappy SO files
* 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)

这个是因为编译的时候带了 native 参数，但是没装autotool。
安装autotool
[zhouhh@h185 hadoop-2.0.1-alpha-src]$ sudo yum install autoconf automake libtool

apache forrest 安装

解压apache-forrest-0.9-dependencies.tar.gz到forrest目录。tools里面的ant等都是dependencies里面带的。
或者用svn去下载最新的版本svn co http://svn.apache.org/repos/asf/forrest/trunk/
修改forrest环境变量
[zhouhh@h185 ~]$ vi .bashrc
export FORREST_HOME=/home/zhouhh/yarn/apache-forrest-0.9

[zhouhh@h185 ~]$ source .bashrc

[zhouhh@h185 findbugs-2.0.1]$ ant
BUILD FAILED
/home/zhouhh/yarn/findbugs-2.0.1/build.xml:166: Problem: failed to create task or type native2ascii
Cause: the class org.apache.tools.ant.taskdefs.optional.Native2Ascii was not found.
This looks like one of Ant’s optional components.
Action: Check that the appropriate optional JAR exists in
-/usr/share/ant/lib
-/home/zhouhh/.ant/lib
-a directory added on the command line with the -lib argument
ant没安装好，到其他地方将ant的库拷贝到/usr/share/ant/lib。该类在ant-nodeps.jar里面。http://labs.mop.com/apache-mirror//forrest/apache-forrest-0.9-dependencies.tar.gz 里面就含有。
redhat和centos自带的ant，在/usr/bin/ant 不能正确编译Findbugs,必须到ant 网站http://ant.apache.org/下载。推荐下载二进制版本。
重新安装ant
