Azure Databricks - ADLS Gen 2.0 Access

[dalion]

Hi all,

I have a Azure Databricks Setup (non-premium) and an ADLS Gen 2.0 setup. I am trying to access the ADLS Gen 2.0 containers via a simple access key mode for testing.

There is no error, if the ADLS Gen 2.0 is set to "Enable from all networks".

But, when it is set to "Enabled from selected virtual and IP Addresses" and "Allow Azure Services on the trusted services list to access this storage account", its doesn't work.

It errors with 403 Get operation error.

Operation failed: "This request is not authorized to perform this operation.", 403, GET, https://xxxxxxxxx.dfs.core.windows.net/raw?upn=false&resource=filesystem&maxResults=5000&timeout=90&..., AuthorizationFailure, "This request is not authorized to perform this operation. RequestId:342de772-c01f-0036-5a58-7553e4000000 Time:2023-04-22T20:24:04.6283599Z"

if you want to put access restrictions on the ADLS, there is some config to do:

Basically you need to tell what is allowed and what isn't.

Hi @Werner Stinckens​  , I have already tried to all the respective IP address. Still its not working.

the Databricks VM's which are provisioned do not have static ip adresses; so you probably have to keep on adding IPs.

Better to use a subnet mask or use a VNet.

Hi @Fabio Santos​ , thanks for the response. All these ADLS Gen 2.0 network setting are set to public. But to secure the customer's data, it should contain a list of Whitelisted IP addresses.
