我正在尝试ssh到Amazon EMR Spark Cluster.这是我做的:

1. 获取集群主机的IP:

   aws emr describe-cluster --cluster-id <cluster_id> | grep MasterPublicDnsName
   

   Run Code Online (Sandbox Code Playgroud)

2. 使用IP ssh到框中:

   ssh -i CSxxx.pem hadoop@ec2-xx-xxx-xxx-xxx.ap-southeast-1.compute.amazonaws.com
   

   Run Code Online (Sandbox Code Playgroud)

我被困在这里,因为跑步(2)给了我以下错误:

ssh: connect to host ec2-xx-xxx-xxx-xxx.ap-southeast-1.compute.amazonaws.com port 22: Operation timed out

有什么想法来解决这个问题？
