This section describes how to enable inter-access between ECS on classic networks and E-MapReduce clusters on VPC networks.
Alibaba Cloud currently provides two types of cloud network: classic and VPC. While some users still use classic networks, E-MapReduce clusters use VPCs.
To grant access between ECS on a classic network and an E-MapReduce cluster on a VPC network, Alibaba Cloud launches ClassicLink. Follow these steps:
- Create a vSwitch according to the CIDR block specified in ClassicLink.
- To deploy a cluster that you have created, use the vSwitch of the CIDR block.
- Connect the corresponding classic network node to the VPC in the ECS console.
- Set the security group rules.
