//64位的linux装的hadoop是32位的---coco

64位的linux装的hadoop是32位的，需要手工编译。
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。
解决办法：重新编译hadoop.//就是重新编译hadoop软件。 (本例文是在从库db99上编译。你也可以在master db96上编译
//只要机器的环境一直。)
下载程序代码：(linux下安装svn)
# yum install svn
[root@db99 data]# /usr/local/svn/bin/svn checkout 'http://svn.apache.org/repos/asf/hadoop/common/tags/release-2.2.0'
[root@db99 release-2.2.0]# ll

安装开发环境
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。
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
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
[root@db99 protobuf-2.5.0]# 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
[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
..............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

测试使用：上传一个文件，下载一个文件，查看上传文件的内容：
[root@db96 ~]# cat wwn.txt

[root@db96 ~]# hdfs dfs -mkdir /test
