32位hadoop编译实现与64位操作系统兼容

没有安装过集群的朋友，可能没有发现，hadoop版本没有64位的，我们在安装hadoop之前需要将hadoop源码包进行编译，否则lib下的部分jar包无法使用【有人可能会说hadoop不分操作系统的bit数，这个问题我有怎么会悄悄告诉你呢！！！！哈哈，开玩笑，接下来，给大家分享一下我第一次编译出现的糗事】
如果不编译会出现啥问题呢？？你可以看俺

遇到的问题描述：
[root@db96 hadoop]# hadoop dfs -put ./in
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.


14/07/17 17:07:22 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
put: `./in': No such file or directory
原因查找：
查看本地文件：
[root@db96 hadoop]# file /usr/local/hadoop/lib/native/libhadoop.so.1.0.0 
/usr/local/hadoop/lib/native/libhadoop.so.1.0.0: ELF 32-bit LSB shared object, 
 Intel 80386, version 1 (SYSV), dynamically linked, not stripped
 是32位的hadoop，安装在了64位的linux系统上。lib包编译环境不一样，所以不能使用。
 悲剧了，装好的集群没法用

【编译环境准备】
要重新指定yum源
网上下载了version-groups.conf到/etc/yum/，删除系统原有的源文件
1. 安装必要的包：
[root@db99 data]# yum install autoconfautomake libtool cmake ncurses-devel openssl-devel gcc* --nogpgcheck


2. 安装maven,下载并解压。（版本不能比这新，有压缩包）
http://maven.apache.org/download.cgi  //下载对应的压缩包
apache-maven-3.2.1-bin.tar
[root@db99 ~]# tar -xvf apache-maven-3.2.1-bin.tar
[root@db99 ~]# tar -xvf apache-maven-3.2.1-bin.tar
[root@db99 ~]# ln -s /usr/local/apache-maven-3.2.1/ /usr/local/maven
[root@db99 local]# vim /etc/profile  //添加环境变量中
export MAVEN_HOME=/usr/local/maven
export PATH=$MAVEN_HOME/bin:$PATH 


3. 安装protobuf（版本不要变，有压缩包）
https://code.google.com/p/protobuf/downloads/detail?name=protobuf-2.5.0.tar.gz
下载：protobuf-2.5.0.tar.gz  并解压
[root@db99 protobuf-2.5.0]# pwd
/root/protobuf-2.5.0
[root@db99 protobuf-2.5.0]# ./configure --prefix=/usr/local/protoc/
[root@db99 protobuf-2.5.0]# make
[root@db99 protobuf-2.5.0]# make check
[root@db99 protobuf-2.5.0]# make install
bin目录下执行 protoc --version
libprotoc 2.5.0
安装成功。
添加环境变量：
vi /etc/profile
export MAVEN_HOME=/usr/local/maven
export JAVA_HOME=/usr/java/latest
export HADOOP_HOME=/usr/local/hadoop
export PATH=.:/usr/local/protoc/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH

4. 编译hadoop（将hadoop源码包解压就会出现如下的包）
[root@db99 release-2.2.0]# pwd
/data/release-2.2.0
[root@db99 release-2.2.0]# ls
BUILDING.txt       hadoop-common-project     hadoop-maven-plugins  hadoop-tools
dev-support        hadoop-dist               hadoop-minicluster    hadoop-yarn-project
hadoop-assemblies  hadoop-hdfs-project       hadoop-project        pom.xml
hadoop-client      hadoop-mapreduce-project  hadoop-project-dist
[root@db99 release-2.2.0]# mvn package -Pdist,native -DskipTests -Dtar （往后看不要急着编译，这是maven命令）
..............编译需要较长时间大概1个小时左右。
如果出现如下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:testCompile (default-testCompile) on project hadoop-auth: Compilation failure: Compilation failure:
[ERROR] /home/hduser/hadoop-2.2.0-src/hadoop-common-project/hadoop-auth/src/test/java/org/apache/hadoop/security/authentication/client/AuthenticatorTestCase.java:[88,11] error: cannot access AbstractLifeCycle

[ERROR] -> [Help 1]


需要修改源码下边的hadoop-common-project/hadoop-auth/pom.xml
vi ~/hadoop-common-project/hadoop-auth/pom.xml
[root@db99 release-2.2.0]# vim /data/release-2.2.0/hadoop-common-project/hadoop-auth/pom.xml 
在第55行下添加：
 56     <dependency>
 57         <groupId>org.mortbay.jetty</groupId>
 58         <artifactId>jetty-util</artifactId>
 59         <scope>test</scope>                                                                          
 60     </dependency>
 保存退出，重新编译即可。
最后编译成功：

此时编译好的文件位于 ~/hadoop-dist/target/hadoop-2.2.0/ 目录中
拷贝hadoop-2.2.0到安装目录下，/usr/local/ 重新修改其配置文件，重新并格式化，启动，即可。
到此已经不会报错，可以使用。
[root@db96 hadoop]# hadoop dfs -put ./in
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.

到此我们的hdfs文件系统已经能正常使用。









按照在64位CentOS上编译 Hadoop 2.2.0的步骤，进行对hadoop2.2在rhel6.2上进行编译，
cd hadoop-2.2.0-src
mvn package -DskipTests -Pdist,native -Dtar
大概10分钟左右时报错如下：
Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.8.1:jar (module-javadocs) on project hadoop-project: Execution ……………………

使用以下命令从新编译：
mvn package -DskipTests -Pdist,native -Dtar -Dmaven.javadoc.skip=true

大概40分钟后，编译完成
