You can even restrict it so that only certain roles within a project (like a data owner) can assume a given role. For the federated IAM role, you create a head IAM role for the cluster that enables Hopsworks to assume a potentially different IAM role in each project. For the per-cluster IAM role, you select an instance profile for your Hopsworks cluster when launching it in Hopsworks, and all jobs or notebooks will be run with the selected IAM role. In Hopsworks, there are two different ways to configure an IAM role: a per-cluster IAM role or a federated IAM role (role chaining). With IAM roles, Jobs or notebooks launched on Hopsworks do not need to explicitly authenticate with Redshift, as the HSFS library will transparently use the IAM role to acquire a temporary credential to authenticate the specified user. The second option is to configure an IAM role. The password is stored in the secret store and made available to all the members of the project. The first option is to configure a username and a password. There are two options available for authenticating with the Redshift cluster. Database port: The port of the cluster.Database name: The name of the database to query.Database endpoint: The endpoint for the database.Database driver: You can use the default JDBC Redshift Driver `42.Driver` (More on this later).
