在 Mac OS 上安装 Hadoop 时出现问题

Question

我正在尝试使用此 instruction 在 Mac os 上安装 hadoop。在这一步sbin/start-dfs.sh，我遇到了问题。我的结果： Starting namenodes on [localhost] Starting datanodes localhost: datanode is running as process 26210. Stop it first. Starting secondary namenodes [https://account.jetbrains.com:443] sed: 1: "s/^/https://account.jet ...": bad flag in substitute command: '/'.

有什么办法吗？真心希望得到您的帮助！

hadoop-env:

#export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-13.0.1.jdk/Contents/Home

已生成 SSH 密钥

ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa 
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys 
chmod 0600 ~/.ssh/authorized_keys

/etc/hosts:

127.0.0.1   localhost 
255.255.255.255 broadcasthost 
::1             localhost 
0.0.0.0 https://account.jetbrains.com:443  
1.2.3.4 account.jetbrains.com  
1.2.3.4 http://www.jetbrains.com  
1.2.3.4 www-weighted.jetbrains.com  
0.0.0.0 account.jetbrains.com

也许 /etc/hosts 有什么错误？

Answer 1

默认情况下，Hadoop 假定 0.0.0.0 将映射到本地连接。

您似乎试图通过修改主机文件来绕过 JetBrains 帐户检查。请像这样恢复您的主机文件

127.0.0.1   localhost
255.255.255.255 broadcasthost
::1             localhost
