How to identify Worker and Driver instance in AWS console for databricks instance?

[Nandhini_Kumar]

For AWS databricks, i have configured 1 worker and 1 driver node with same node type. 
In the AWS console, all details are same for the two instance, as instance id only different. How to identify which instance id is for worker and which one is for driver.

Hi @Nandhini_Kumar, 

• If you’ve configured instance pools, you can use the instance pool ID to differentiate between worker and driver nodes.
• Specifically:
  • If you have a driver_instance_pool_id, that ID corresponds to the driver node.
  • Otherwise, the instance_pool_id is used for both the driver and worker nodes^1.
    
    
    Each Databricks workspace has a unique workspace ID.
    • If your deployment URL contains a parameter like o=6280049833385130, the random number after o= repr...².
    • Alternatively, you can retrieve the workspace ID from within a notebook by running the following command in a Python or Scala cell:To find it:

      spark.conf.get("spark.databricks.clusterUsageTags.clusterOwnerOrgId")
      

      This command will return the workspace ID³.

Hi @Kaniz_Fatma Thanks for your response.

There is no instance pool ID while configured the cluster, then how will i able to differentiate then.
Could you give any alternative way for finding the driver instance id and worker instance id in the AWS console.
