hadoop - 尝试打开 Hadoop 时，我在 Google Cloud 终端中不断收到 "Permission Denied"

Question

我正在尝试在 GCP 上运行 Hadoop。每当我输入命令时start-dfs.ssh && start-yarn我得到以下......

localhost: chuckpryorjr@localhost: Permission denied (publickey).
localhost: chuckpryorjr@localhost: Permission denied (publickey).
Starting secondary namenodes [0.0.0.0]
0.0.0.0: chuckpryorjr@0.0.0.0: Permission denied (publickey).
starting yarn daemons
starting resourcemanager, logging to /usr/local/hadoop-ecosystem/hadoop-2.9.2/logs/yarn-chuckpryorj
r-resourcemanager-hadoopmasters.out
localhost: chuckpryorjr@localhost: Permission denied (publickey).

我不明白。在他们过去常常提示我输入密码(我不记得曾经做过)之前，现在它完全拒绝了我。如何使这个无密码？我也是第一次在 GCP 上安装 hadoop 并运行它。它运行良好。有时我可以完成我的工作..有时我不能。

How can make this passwordless?

  $ ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa

然后为 localhost 更新您的本地授权 key 文件

  $ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
  $ chmod 0600 ~/.ssh/authorized_keys

如果你有其他服务器，你可以使用 ssh-copy-id把 key 放进那些
