  • Hi Vipin,

    When submitting a job on Azure Data Lake Analytics (ADLA) via Azure Data Factory (ADF), it is not enough for you (the user) to have access to the ADLA account (as you do since you can submit the job yourself).  You have to give the data factory permissions to submit jobs on the ADLA account as well.  

    You can do this through Managed Service Identity authentication or Service Principal authentication.  For MSI, you assign permissions in ADLA directly to your data factory.  For SP, you create a web app (through AAD) and give it access to your ADLA account, and pass the app's key and id to your data factory.

    Please let me know if this works, and if not we can debug further.

    To build on MattBasile_MSFT's answer, I was able to follow the documentation here and get my ADLA linked service working:
