I"m trying to mount azure storage blob into azure Databricks using python notebook using below code.

mount_name = '/mnt/testMount'

if not any(mount.mountPoint == mount_name for mount in dbutils.fs.mounts()):              
    dbutils.fs.mount(
        source = "wasbs://%s@%s.blob.core.windows.net" % (container, accountName),
        mount_point = mount_name,
        extra_configs = {"fs.azure.account.key.%s.blob.core.windows.net" % (accountName ) : accountKey })

Mount was successful and I was able to see using print(dbutils.fs.mounts()) also using DBFS CLI in my linux VM. dbfs ls dbfs:/mnt/testMount

But not visible in the UI nor accessible from python notebook FileNotFoundError: [Errno 2] No such file or directory: '/mnt/testMount/'.

Can someone please let me know if you faced this issue and what is the fix?

I really recommended you can read the section Managed and unmanaged tables of the offical document User Guide > Databases and Tables.

enter image description here

So you mount Azure Blob Storage to DBFS as a part of filesystem of Azure Databricks which is belong to unmanaged table that be created by coding in notebook.

In Azure databricks, you need to provide the path in Jyupter Notebook as "dbfs:/mnt/azureblobshare/<your_file_name_with_extension>"

Example: If I upload a file "MyFile.txt" then the file path in Jyupter notebook will be

filePath="dbfs:/mnt/azureblobshare/MyFile.txt"

This should work for you.
