docker安装单机hadoop

docker安装单机hadoop

#下载hadoop镜像
docker pull sequenceiq/hadoop-docker:2.6.0

#查看镜像
docker images

#运行hadoop
docker run -i -t -p 50070:50070 -p 9000:9000 -p 8088:8088 -p 8040:8040 -p 8042:8042  -p 49707:49707  -p 50010:50010  -p 50075:50075  -p 50090:50090 sequenceiq/hadoop-docker:2.6.0 /etc/bootstrap.sh -bash

先进入hadoop容器
docker exec -it ${CONTAINER ID} /bin/bash
执行完成docker run 也就是上一步,该步骤可以省略

cd /usr/local/hadoop-2.6.0
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0.jar grep input output 'dfs[a-z.]+'

如果执行mapreduce程序说明安装成功
可以打开浏览器查看
宿主机IP:50070
docker安装完毕
为了正常使用还需安装以下东西

vi /etc/profile
在最底部加入下面内容

export HADOOP_HOME="/usr/local/hadoop"
export PATH=$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH

保存:wq
使得配置生效

source /etc/profile

hadoop version

再次启动：

docker ps -a 
docker start ${CONTAINER ID}
