I wanted to mount a ADLG2 on databricks and take advantage on the abfss driver which should be better for large analytical workloads (is that even true in the context of DB?).

Setting an OAuth is a bit of a pain so I wanted to take the simpler approach and use a Shared Key. Following what I've seen in Hadoop documentation this should work, any ideas of what I might be doing wrong? I get a `java.lang.NullPointerException: authEndpoint` error.

%py
dbutils.fs.mount(
  source = "abfss://"+ container + "@" + storageAccountName + ".dfs.core.windows.net",
  mount_point = "/mnt/" + container,
  extra_configs = {'fs.azure.account.auth.type.' + storageAccountName + '.dfs.core.windows.net': "SharedKey",
                   'fs.azure.account.key.' +       storageAccountName + '.dfs.core.windows.net': storageAccountAccessKey})
