Docker部署Hadoop集群

因为原作者写的很好，这里直接贴链接。

里面下载安装jdk和hadoop没有给，这里我把我找的链接贴进来。

wget http://mirrors.hust.edu.cn/apache/hadoop/common/hadoop-2.7.4/hadoop-2.7.4.tar.gz
wget http://download.oracle.com/otn-pub/java/jdk/8u151-b12/e758a0de34e24606bca991d704f6dcbf/jdk-8u151-linux-x64.tar.gz?AuthParam=1509888692_a5642d04abe8db4534c4699dc902165b

因为我下载和给的不一样。所以DockerFile也需要改一下：

FROM centos7-ssh
ADD jdk-8u151-linux-x64.tar.gz /usr/local/
RUN mv /usr/local/jdk1.8.0_151 /usr/local/jdk1.8
ENV JAVA_HOME /usr/local/jdk1.8
ENV PATH $JAVA_HOME/bin:$PATH

ADD hadoop-2.7.4.tar.gz /usr/local
RUN mv /usr/local/hadoop-2.7.4 /usr/local/hadoop
ENV HADOOP_HOME /usr/local/hadoop
ENV PATH $HADOOP_HOME/bin:$PATH

RUN yum install -y which sudo
