Hadoop GCE主VM ssh到从VM，然后显示权限被拒绝（公钥）,hadoop,ssh,google-compute-engine,Hadoop,Ssh,Google Compute Engine,我试图构建Hadoop集群（一个主集群和一个从集群），所以我在GCE创建了两个实例首先，我在主机上使用ssh-keygen命令： ssh-keygen -t rsa -P "" 然后我将~/.ssh/id\u rsa.pub复制到授权密钥之后，我将~/.ssh/authorized_密钥从主机复制到从机的~/.ssh/ 当我开始在master上使用ssh slave-v时，出现了如下错误： hadoop_admin@master:~/.ssh$ ssh slave -v

我试图构建Hadoop集群（一个主集群和一个从集群），所以我在GCE创建了两个实例

首先，我在主机上使用

ssh-keygen

命令：

ssh-keygen -t rsa -P ""

然后我将

~/.ssh/id\u rsa.pub

复制到

授权密钥

之后，我将

~/.ssh/authorized_密钥

从主机复制到从机的

~/.ssh/

当我开始在master上使用

ssh slave-v

时，出现了如下错误：
