将文件从本地计算机复制到 docker 容器
Copy a file from local machine to docker container
我正在关注 this 示例：
我发现 namenode 如下：
(dash_apps_36) idf@ubvm:~/Documents/docker-hadoop$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

使用7fc72b887e23作为namenode的ID，当我得到命令
$ docker cp ../hadoop-mapreduce-examples-2.7.1-sources.jar cb0c13085cd3:hadoop-mapreduce-examples-2.7.1-sources.jar
我得到一个错误：
$: command not found
不确定我做错了什么。
去掉开头的$。这就是 $: command not found 的意思。复制粘贴代码容易漏掉
docker cp ../hadoop-mapreduce-examples-2.7.1-sources.jar cb0c13085cd3:hadoop-mapreduce-examples-2.7.1-sources.jar
