Hadoop2.2版本编译运行

一编译环境：
centos5.10 64Bit，
jdk 1.6.0_45
maven 3.1.1
protoc2.5.0

二基础环境配置：

1、安装JDK

1.1:
vi .bash_profile:

export PATH
export JAVA_HOME=/data/server/1.6.0_45
export PATH=$JAVA_HOME/bin:$PATH #首先从JAVA_HOME下寻找可调用的java可执行程序，否则再调用centos自带的openjdk

source .bash_profile

测试下JDK是否安装成功: java -version

java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

2、编译前的准备(maven)

maven官方下载地址，可以选择源码编码安装，这里就直接下载编译好的就可以了

wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.1.1/binaries/apache-maven-3.1.1-bin.zip
解压文件后，同样在.bash_profile里配置环境变量
export MAVEN_HOME=/opt/maven3.1.1
export PATH=$PATH:$MAVEN_HOME/bin

验证配置是否成功: mvn -version:

Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 23:22:22+0800)
Maven home: /data/server/apache-maven-3.1.1
Java version: 1.6.0_45, vendor: Sun Microsystems Inc.
Java home: /data/server/jdk1.6.0_45/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.18-371.11.1.el5", arch: "amd64", family: "unix"

3、编译hadoop

首先官方下载hadoop源码

wget http://mirrors.cnnic.cn/apache/hadoop/common/hadoop-2.2.0/hadoop-2.2.0-src.tar.gz
如果是你32bit的机器，可以直接下载官方已经编译好的包，64bit的机子跑编译好的包跑不了。
由于maven国外服务器可能连不上，先给maven配置一下国内镜像，在maven目录下，conf/settings.xml,在<mirrors></mirros>里添加，原本的不要动

<mirror>
<id>nexus-osc</id>
<mirrorOf>*</mirrorOf>
<name>Nexusosc</name>
<url>http://maven.oschina.net/content/groups/public/</url>
</mirror>

4.其他环境的配置；
hadoop2.2.0编译需要protoc2.5.0的支持，所以还要下载protoc，下载地址:https://code.google.com/p/protobuf/downloads/list，要下载2.5.0版本
对protoc进行编译安装前先要装几个依赖包:gcc,gcc-c++,make 如果已经安装的可以忽略

安装protoc
tar -xvf protobuf-2.5.0.tar.bz2
cd protobuf
make && make install
安装完配置下环境变量，就不多说了，跟上面过程一样。

yum install gcc
yum intall gcc-c++
yum install make

yum install cmake
yum install openssl-devel
yum install ncurses-devel

5. 编译打包
5.1 编译clean

cd hadoop2.2.0-src
mvn clean install –DskipTests

如果遇到以下报错:
[ERROR] class file for org.mortbay.component.AbstractLifeCycle not found
这次是遇到BUG了按照https://issues.apache.org/jira/browse/HADOOP-10110
下载HADOOP-10110.patch，然后把该patch打上去，修正该bug

5.2 如果mvn clean install 顺利完成，则进行打包：
mvn package -Pdist,native -DskipTests -Dtar

如果顺利的话，如下显示：

直到看到上面的内容那就说明编译完成了。
编译后的路径在:hadoop-2.2.0-src/hadoop-dist/target/hadoop-2.2.0

[root@localhost bin]# ./hadoop version
Hadoop 2.2.0
Subversion Unknown -r Unknown
Compiled by root on 2013-11-22T08:47Z
Compiled with protoc 2.5.0
From source with checksum 79e53ce7994d1628b240f09af91e1af4
This command was run using /data/hadoop-2.2.0-src/hadoop-dist/target/hadoop-2.2.0/share/hadoop/common/hadoop-common-2.2.0.jar

可以看出hadoop的版本
[root@localhost hadoop-2.2.0]# file lib//native/*
lib//native/libhadoop.a: current ar archive
lib//native/libhadooppipes.a: current ar archive
lib//native/libhadoop.so: symbolic link to `libhadoop.so.1.0.0'
lib//native/libhadoop.so.1.0.0: <span style="color:#ff0000;">ELF 64-bit LSB shared object, x86-64, version 1</span> (SYSV), dynamically linked, not stripped
lib//native/libhadooputils.a: current ar archive
lib//native/libhdfs.a: current ar archive

lib//native/libhdfs.so.0.0.0: <span style="color:#ff0000;">ELF 64-bit LSB shared object, x86-64, version 1</span> (SYSV), dynamically linked, not stripped

hadoop-2.2.0-src/hadoop-dist/target下的hadoop-2.2.0 则为最终自行编译生成的可执行的64bit 环境下的hadoop版本，能支持apache官方下载的hbase-0.98版本
