Create a Managed Private Endpoint to Blob endpoint in Azure Synapse

NC 31

Hi,
Getting error "Name or Service not know" when mounting ADSL in Synapse notebook with Microsoft Spark Utilities with Managed Virtual Network and Data Exfiltration Protection enabled.

mssparkutils.fs.mount(
"abfss://mycontainer@<accountname>.dfs.core.windows.net",
"/data",
{"linkedService":linkservice}
)

When i run the code above I got "Name or Service not know"

We create two private endpoints one with dfs and one with blob.

As @ShaikMaheer mentioned in this forum before that we need to create a Managed Private Endpoint to Blob endpoint. I did try that but when I create a manage private endpoint in Synapse workspace.

then choosed which datalake I want to use and create it. I got dfs as a default. Not so sure how can I create a MPE with blob endpoint. Could you show me how to do that?

Hi @ChanprasertNudjaree-2315 ,

Thank you for posting query in Microsoft Q&A Platform.

From your screenshot it seems you tried to use ADLS gen2 type connector while creating Managed Private end point. Kindly try picking Azure Blob storage type connector while creating Managed Private end point and see if that helps?

Please let us know how it goes, Thank you.

It works with Blob Managed private endpoint but when I try to list all the files from mount path I got this error.

mssparkutils.fs.mount("synfs:/"+jobID+"/raw/QMS/TDMS"+station)

Hi @ChanprasertNudjaree-2315 , Glad to know that it worked and your able to create Managed Private end point for blob. Please consider hitting Accept Answer button. Accepted answers helps community as well.

Regarding, follow up query, From error message it seems path given to mssparkutils.fs.ls() is not found. I assume below may be one of reasons so could you please cross check point and see.

The path getting computed from your code may incorrect. Could you please recheck is your mount point created with name /raw and then remaining path following as continuation to the path from mount point path?

Kindly make sure mount point created successfully and immediately you are running above code to list files in a path.

Kindly make sure the path which you are trying to check is really exists in your storage.

Below video has details about creating mount point and then using mount point for further actions explained. Kindly check if that helps.
