Synapse Spark: mssparkutils.fs.mount - Access token couldn't be obtained

Jason Campbell 51

mssparkutils.fs.mount(   
    "abfss://******@mydatalake.dfs.core.windows.net",   
    "/temp",   
    {"linkedService":"DataLakeGen2_Linked_Service"}   
)

When I run the above it gives me:

Py4JJavaError: An error occurred while calling z:mssparkutils.fs.mount.
: com.microsoft.spark.notebook.msutils.InvalidCredentialsException: fetch Token from linkedService failed with Access token couldn't be obtained {"result":"DependencyError","errorId":"BadRequest","errorMessage":"LSRServiceException is [{\"StatusCode\":400,\"ErrorResponse\":{\"code\":null,\"message\":null,\"target\":null},\"StackTrace\":\"

Any ideas?
The linked service works fine. Test connection is successful.

thanks,
Jason

I was able to mount the storage when I used a linked service that used a private endpoint. Looks like my organisation had locked down the linked service that was missing the private endpoint.

Now that it's mounted, the Geopandas read is still not seeing the file as if it was on the local storage. Mounting the storage should have worked - or is there another consideration that I am missing?

e.g.

mssparkutils.fs.mount(
"abfss://******@mydatalake.dfs.core.windows.net",
"/temp",
{"linkedService":"DL_Linked_Service"}
)

Hello @Jason Campbell ,

Thank you for question and using Microsoft Q&A Platform.

You may experience the above error message occurs when we misspell or provide incorrect details in mount point creation code.

Kindly make sure below checkpoints are correct to make your code:

Make sure your linked service test connection is successful.
Make sure linked service name in the mount point creation code is correct.
Make sure path of your storage account is correct without any spaces and spelling mistakes.

Hope this will help. Please let us know if any further queries.
