Ubuntu12.04-x64编译Hadoop2.2.0和安装Hadoop2.2.0集群

•JavaScript•阅读 2601

　　本文Blog地址：http://www.cnblogs.com/fesh/p/3766656.html

　　本文对Hadoop-2.2.0源码进行重新编译（64位操作系统下不重新编译会有版本问题），并构建Hadoop-2.2.0集群，生成在Eclipse环境上的Hadoop-2.2.0插件，并通过了测试运行。

1 、 安装maven 、libssl-dev 、cmake 和JDK

安装本机库http://wiki.apache.org/hadoop/HowToContribute

sudo apt-get -y install maven build-essential autoconf automake libtool cmake zlib1g-dev pkg-config libssl-dev
sudo tar -zxvf jdk-7u51-linux-x64.tar.gz /usr/lib/jvm/
sudo gedit /etc/profile

For RHEL (and hence also CentOS):

yum -y install  lzo-devel  zlib-devel  gcc autoconf automake libtool openssl-devel

还要安装cmake，不然会报错 Cannot run program "cmake" (in directory "/opt/hadoop-2.5.1-src/hadoop-common-project/hadoop-common/target/native"): error=2, No such file or directory

yum install cmake

然后，添加

#set Java Environment

export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_51
export CLASSPATH=.:$JAVA_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$PATH

设置默认JDK版本

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_51/bin/java 300
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.7.0_51/bin/javac 300
sudo update-alternatives --config java

使设置生效

source /etc/profile

2 、安装ProtocolBuffer

下载https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz

tar -zxvf protobuf-2.5.0.tar.gz
cd protobuf-2.5.0
sudo ./configure
sudo make
sudo make check
sudo make install
sudo ldconfig
protoc --version

对于CentOS系统，也可以使用

yum install protobuf

3 、安装FindBugs

下载http://sourceforge.net/projects/findbugs/files/findbugs/2.0.3/findbugs-2.0.3.tar.gz

解压

tar -zxvf findbugs-2.0.3.tar.gz
sudo gedit /etc/profile

添加

#set Findbugs Environment

export FINDBUGS_HOME=/home/hadoop/findbugs-2.0.3
export PATH=$FINDBUGS_HOME/bin:$PATH
source /etc/profile

4、安装Maven

下载 http://mirrors.cnnic.cn/apache/maven/maven-3/3.2.3/binaries/apache-maven-3.2.3-bin.tar.gz

解压，然后配置/etc/profile

#Set Maven
export M2_HOME=/opt/maven
export PATH=$PATH:$M2_HOME/bin
source /etc/profile
mvn -v

4 、编译Hadoop-2.2.0

①下载http://mirrors.cnnic.cn/apache/hadoop/common/hadoop-2.2.0/hadoop-2.2.0.tar.gz

②解压 
tar -zxvf hadoop-2.2.0-src.tar.gz
③添加jetty-util依赖Index: hadoop-common-project/hadoop-auth/pom.xml

在

<dependency>
      <groupId>org.mortbay.jetty</groupId>
       <artifactId>jetty</artifactId>
       <scope>test</scope>
</dependency>

前添加

<dependency>
       <groupId>org.mortbay.jetty</groupId>
      <artifactId>jetty-util</artifactId>
      <scope>test</scope>
</dependency>

④执行编译

cd hadoop-2.2.0-src
mvn clean package -Pdist,native -DskipTests -Dtar -e -X

（可以不要clean、-e -X）

Ubuntu12.04-x64编译Hadoop2.2.0和安装Hadoop2.2.0集群

5、安装Hadoop集群

①这里总共2台主机，在2台主机上创建相同的用户hadoop，在每一台主机上，配置主机名和IP地址，打开每个主机的/etc/hosts文件，输入(这里IP地址根据每台主机的具体IP地址进行设定，可以设置静态IP，可以在master上ping一下slave的地址，看看是否能通信。把ipv6等设置删去)

127.0.0.1      localhost
192.168.116.133      master
192.168.116.134 slave1

并分别修改各自的/etc/hostname文件内容为master、slave1

②安装SSH，设置SSH免密码登录（JDK安装在这里不详述了）

sudo apt-get install ssh
ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
ssh -version
ssh localhost

注：将节点A的authorized_keys放到节点B的authorized_keys中，则节点A可以免密码访问节点B

将文件从master复制到slave主机的相同文件夹内

cd .ssh
scp authorized_keys slave1:~/.ssh/

（输入ssh slave1查看是否可以从master主机免密码登录slave1

可以从master上切换到slave1主机，输入exit返回到master主机）

③解压编译好的hadoop

tar -zxvf hadooop-2.2.0.tar.gz

添加环境变量

sudo gedit /etc/profile

添加代码

export HADOOP_HOME=/home/hadoop/hadoop-2.2.0
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin

使配置生效

sudo source /etc/profile

④修改配置文件

这些配置参考过官网

cd /hadoop-2.2.0/etc/hadoop

文件hadoop-env.sh
