Reference documentation and code samples for the Google Cloud Dataproc v1 API enum GkeNodePoolTarget.Types.Role.
Role specifies the tasks that will run on the node pool. Roles can be
specific to workloads. Exactly one
[GkeNodePoolTarget][google.cloud.dataproc.v1.GkeNodePoolTarget] within the
virtual cluster must have the DEFAULT role, which is used to run all
workloads that are not associated with a node pool.
Run work associated with the Dataproc control plane (for example,
controllers and webhooks). Very low resource requirements.
Default
At least one node pool must have the DEFAULT role.
Work assigned to a role that is not associated with a node pool
is assigned to the node pool with the DEFAULT role. For example,
work assigned to the CONTROLLER role will be assigned to the node pool
with the DEFAULT role if no node pool has the CONTROLLER role.
SparkDriver
Run work associated with a Spark driver of a job.
SparkExecutor
Run work associated with a Spark executor of a job.
