Error while mounting ADLS in python using AccountKey

[Krish1]

I'm using the below code using Account key to mount ADLS in python but running into error:shaded.databricks.org.apache.hadoop.fs.azure.AzureException: java.lang.IllegalArgumentException: The String is not a valid Base64-encoded string. Can you please help?

AccountKey = dbutils.secrets.get(scope="ADB_KV_Secret_Scope", key="dev-storage-account-clientid")

url = "wasbs://dev@storage.blob.core.windows.net"

mnt = "/mnt/findatamart"

configs =  "fs.azure.account.key.storage.blob.core.windows.net"

dbutils.fs.mount(

  source = url,

  mount_point = mnt,

  extra_configs ={configs:AccountKey}

  )

@Krish Lam​ you need to provide more details for the config. Please refer to the below doc.

configs = {"fs.azure.account.auth.type": "OAuth",

     "fs.azure.account.oauth.provider.type": "org.apache.hadoop.fs.azurebfs.oauth2.ClientCredsTokenProvider",

     "fs.azure.account.oauth2.client.id": "<application-id>",

     "fs.azure.account.oauth2.client.secret": dbutils.secrets.get(scope="<scope-name>",key="<service-credential-key-name>"),

     "fs.azure.account.oauth2.client.endpoint": "https://login.microsoftonline.com/<directory-id>/oauth2/token"}

# Optionally, you can add <directory-name> to the source URI of your mount point.

dbutils.fs.mount(

 source = "abfss://<container-name>@<storage-account-name>.dfs.core.windows.net/",

 mount_point = "/mnt/<mount-name>",

 extra_configs = configs)

Replace

• <application-id> with the Application (client) ID for the Azure Active Directory application.
• <scope-name> with the Databricks secret scope name.
• <service-credential-key-name> with the name of the key containing the client secret.
• <directory-id> with the Directory (tenant) ID for the Azure Active Directory application.
• <container-name> with the name of a container in the ADLS Gen2 storage account.
• <storage-account-name> with the ADLS Gen2 storage account name.
• <mount-name> with the name of the intended mount point in DBFS.
