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}
)

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.
