ADF Pipeline Error:
ADF Pipeline Error 2703, Data Lake Analytics job failed

What does this error mean?

Data Lake Analytics job submitted via ADF failed with an internal U-SQL/CQO error (Error Id starts with 'Error Id:').

Common causes

• 1U-SQL script failure inside Data Lake Analytics (compilation, runtime or vertex error).
• 2Internal CQO/system error in the Data Lake Analytics service (E_CQO_SYSTEM_INTERNAL_ERROR).
• 3Service principal or certificate used by ADF lacks access to the ADLA account or referenced storage.
• 4Transient ADLA platform issue requiring Microsoft support with the job URL.

How to fix it

1. 1Open the Data Lake Analytics account in the Azure portal and locate the job using the ADF activity run ID (not the pipeline run ID).
2. 2Inspect the job's error details, script, and vertex logs in ADLA to identify the underlying U-SQL or system error.
3. 3Verify that the service principal/certificate configured in the ADF linked service has access to both the ADLA account and the linked storage.
4. 4If the error remains an internal 'Error Id:' message, contact Data Lake Analytics support with the full job URL (account name + job ID).
5. 5Re-run the ADF pipeline once the underlying ADLA job issue is resolved.
