In Azure Synapse monitor Apache Spark Applications who or what is the submitter GUID?

Question

In Synapse studio monitor Apache Spark Applications the same GUID - 2864980c-2195-47d6-bc42-d8b4ff8e3e11 - appears many times as the submitter and I cannot find out who or what this is.

I have tried >az ad sp show --id 2864980c-2195-47d6-bc42-d8b4ff8e3e11

Resource '2864980c-2195-47d6-bc42-d8b4ff8e3e11' does not exist or one of its queried reference-property objects are not present.

and az ad user show but get the same error

Please can you suggest how to find out what this GUID relates to if not an SP or user?

Answer 1

The Submitter GUID represents the user or service that submitted the Spark job. In this case, the application name suggests the job was triggered from a Synapse notebook or another code-driven interface within Synapse.

Here, the Submitter acts as a unique identifier for the application — specifically, it's the Admin Object/App ID from the Synapse Workspace's Microsoft Entra ID, as shown in the image below.

Whenever you run a notebook in Synapse, the platform automatically generates an application ID, whether the job is submitted by a user, a managed identity, or a service principal, and records that identity as the Submitter GUID.

If you are not able to access this sensitive information, then you might not have correct privileges or you are not the owner of the workspace. So, you will be blocked from every other cases.

But if you are the owner of workspace you will get to see the information Microsoft Entra ID. If you still need the information to verify connect with the owner of workspace.

Here is the way you can find the owner of synapse workspace:

 @Cooke, Richard (Allianz UK)

A GUID (Globally Unique Identifier) is significant because it provides a way to uniquely identify entities across systems, without relying on centralized coordination.It’s a 128-bit value used to uniquely identify information across systems.
Generate a globally unique identifier (GUID) as a string, for example, "c2ecc88d-88c8-4096-912c-d6f2e2b138ce":

In Azure Synapse, a Submitter GUID typically refers to the unique identifier of the identity (user or service principal) that submitted or triggered a specific operation like a pipeline run, notebook execution, or Spark job.

Where You Might See "Submitter GUID":

• Pipeline Run metadata
• Monitoring logs / Activity runs
• Spark job metadata
• Synapse Workspace audit logs

In pipeline run metadata, you might see fields like:

"runId": "0d7e8f1a-7b5d-4f4b-b32c-bf5f0b90a983",
"submitter": {
  "name": "******@domain.com",
  "id": "a1234567-b89c-40de-9abc-0123456789ef"  <-- This is the Submitter GUID
}

If you have a specific UI screenshot, pipeline run log, or JSON about Submitter GUID I can confirm the exact meaning
