问题描述
我要创造一个没有任何实例分配一个公网IP地址，出于安全原因的EMR集群。我已经能够推出集群中我VPC，用我自己的自定义安全组，但由于某些原因，所有的节点都在默认情况下分配一个公网IP地址。
I wish to create an EMR cluster where none of the instances are assigned a public IP address for security reasons. I have been able to launch the cluster in my VPC, and using my own custom security group, but for some reason all the nodes are assigned a public IP address by default.
我无法找到EMR CLI文档有关如何禁用此任何东西：的
I cant find anything in the EMR CLI documentation about how to disable this: http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/emr-cli-commands.html
任何想法？有一些EMR具体原因的情况下，必须有一个公网IP？
Any ideas? Is there some EMR specific reason why the instances MUST have a public IP?
推荐答案
目前需要的电子信息产品通过互联网网关来访问S3，请参阅：的
Currently EIPs are needed to access S3 through the Internet Gateway, see:http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/emr-plan-vpc-subnet.html
目前还不支持完全私人簇。
Completely private clusters are not yet supported.
