Allow the self-service cluster to access data sources so that it can read and write data in mappings.
A self-service cluster accesses data sources using the connections that you configure in your organization. If the connection requires you to create an IAM role or a managed identity, allow the cluster to use it based on the cloud platform:
On AWS, attach the IAM role to the Kubernetes user-managed service account.
On Microsoft Azure, assign the managed identity to the Secure Agent machine.
If you configure a managed identity for an Azure ADLSGen2 connection, make sure the managed identity is assigned to every cluster node where data integration jobs can run.
