ADF Pipeline Error:
ADF Pipeline Error 2304

What does this error mean?

Storage linked service used by an HDInsight linked service or HDI activity is configured with MSI authentication, which is not supported.

Common causes

• 1Storage linked service for the HDI linked service uses MSI (Managed Identity) authentication
• 2Storage linked service referenced by an HDI activity uses MSI authentication
• 3HDInsight cluster configured to access ADLS/Blob via Managed Identity instead of key-based auth
• 4Linked service migrated from key auth to MSI without checking HDI compatibility

How to fix it

1. 1Open the storage linked service used by your HDInsight linked service or HDI activity in ADF.
2. 2Change the authentication method from Managed Identity to a full connection string (account key or SAS).
3. 3Update the HDInsight linked service to reference the reconfigured storage linked service.
4. 4Validate and republish the pipeline, then trigger a test run to confirm the HDI activity authenticates successfully.
5. 5If MSI is required for governance, isolate HDI workloads onto a separate storage account that uses key-based auth.
