Ubuntu 12.04上安装Hadoop并运行

作者：凯鲁嘎吉 - 博客园 http://www.cnblogs.com/kailugaji/

在官网上下载好四个文件

在Ubuntu的/home/wrr/下创建一个文件夹java，将这四个文件拷到Ubuntu的/home/wrr/java/下，将eclipse、hadoop-2.7.6与jdk进行解压，将.iar文件复制到eclipse/plugins，将/jdk1.8.0_191/下的jre文件夹拷到eclipse中，如下图所示

在/home/wrr/下新建文件夹data，里面新建三个文件夹data、name与tmp，创建文件夹的命令：sudo mkdir java

添加环境变量

sudo gedit ~/.bashrc

打开.bashrc，在后面添加环境变量

export JAVA_HOME=/home/wrr/java/jdk1.8.0_191

export JRE_HOME=/home/wrr/java/jdk1.8.0_191/jre

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib

export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

export HADOOP_HOME=/home/wrr/java/hadoop-2.7.6

export PATH=$PATH:$HADOOP_HOME/bin

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native

再键入

source ~/.bashrc

此时环境变量添加成功，现在输入hadoop version 与 java -version来查看版本。

配置/home/wrr/java/hadoop-2.7.6/etc/hadoop下的集群参数

启动hadoop。首先导入/home/wrr/java/hadoop-2.7.6/sbin一下目录，再启动namenode，datanode与yarn

wrr@ubuntu:~$ cd /home/wrr/java/hadoop-2.7.6/sbin

wrr@ubuntu:~/java/hadoop-2.7.6/sbin$ jps

6559 Jps

wrr@ubuntu:~/java/hadoop-2.7.6/sbin$ ./hadoop-daemon.sh start datanode

starting datanode, logging to /home/wrr/java/hadoop-2.7.6/logs/hadoop-wrr-datanode-ubuntu.out

wrr@ubuntu:~/java/hadoop-2.7.6/sbin$ ./start-yarn.sh

starting yarn daemons

starting resourcemanager, logging to /home/wrr/java/hadoop-2.7.6/logs/yarn-wrr-resourcemanager-ubuntu.out

localhost: ssh: connect to host localhost port 22: Connection refused

wrr@ubuntu:~/java/hadoop-2.7.6/sbin$ ./hadoop-daemon.sh start namenode

starting namenode, logging to /home/wrr/java/hadoop-2.7.6/logs/hadoop-wrr-namenode-ubuntu.out

wrr@ubuntu:~/java/hadoop-2.7.6/sbin$ jps

6978 NameNode

6692 ResourceManager

7013 Jps

6587 DataNode

都启动之后，在浏览器上输入http://localhost:18088，即可出现如下界面

停止hadoop

wrr@ubuntu:~/java/hadoop-2.7.6/sbin$ ./hadoop-daemon.sh stop namenode

wrr@ubuntu:~/java/hadoop-2.7.6/sbin$ ./hadoop-daemon.sh stop datanode

wrr@ubuntu:~/java/hadoop-2.7.6/sbin$ ./stop-yarn.sh

wrr@ubuntu:~/java/hadoop-2.7.6/sbin$ jps

7259 Jps
