Call the JoinResourceGroup operation to add EMR-related resources to a resource group.

A resource is a cloud service entity that you create on Alibaba Cloud. E-MapReduce cloud resources that support resource groups are clusters and projects. When a cluster is added to a resource group, the ECS instances of each node in the cluster are added to the resource group to which the cluster belongs. A resource group is a collection of infrastructure for projects, environments, or stacks. In a resource group, you can manage resources and monitor and run tasks in a centralized manner without switching between Alibaba Cloud services.
