Managing SSH credentials
SSH credentials allow securely connecting to machines without repeatedly entering credentials for each DataStax Enterprise (DSE) install, configure, or import job.
Lifecycle Manager logs in to machines with the specified credentials when running jobs. Specify an SSH credential at the cluster, datacenter, or node level. An SSH credential applied at the cluster level is used to log in to all machines associated with the cluster. Applying a credential at the datacenter level overrides any cluster-level credentials and applies to all nodes associated with the datacenter. A credential applied at the node level has the highest possible precedence. Define unique SSH credentials as needed for your cluster topologies.
If there are any SSH connection issues when running a job, increase the SSH connection settings for Lifecycle Manager.
