docker安装hadoop

docker-compose快速搭建hadoop

引用：https://www.jianshu.com/p/9b548517abbb

说明：所有的启动所需的文件(docker-compose.yml和hadoop.env)必须在同一个目录下否则docker compose找不到报错，hadoop目录可以自定义映射，建议也放在同一个目录下。安装docker compose装前需安装docker。

1.安装docker compose

# 安装到目录/usr/local/bin/
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

2.创建目录/data/docker-compose/hadoop-3.2.1并创建两个文件docker-compose.yml和hadoop.env

docker-compose.yml

version: "3"

services:
  namenode:
    image: bde2020/hadoop-namenode:2.0.0-hadoop3.2.1-java8
    container_name: namenode

    env_file:

    env_file:
