在使用python的databricks中，dbutils.fs.mount给出java.lang.NullPointerException:authEndpoint尝试使用abfss装载。黄蜂很好用

在DataRicks中使用db.fs.mount连接到azure gen2 data lake时，在尝试连接到“”时收到authEndpoint错误abfss://theDir@Atalake.blob.core.windows.net/“但是，正在连接到”wasbs://theDir@Atalake.blob.core.windows.net/“运行良好。我试图理解为什么abfss会导致authEndpoint错误，而wasbs不会

enter code here
#fails
endpoint = "abfss://theDir@theDataLake.blob.core.windows.net/";
dbutils.fs.mount(
   source = endpoint,
   mount_point = "/mnt/test",
   extra_configs = {"fs.azure.account.key.theDataLake.blob.core.windows.net" : "xxxxxx"})

#works
endpoint = "wasbs://theDir@theDataLake.blob.core.windows.net/";
dbutils.fs.mount(
   source = endpoint,
   mount_point = "/mnt/test",
   extra_configs = {"fs.azure.account.key.theDataLake.blob.core.windows.net" : "xxxxxx"})

无法使用存储密钥装载ABFSS协议。只有在使用服务主体（）时，才能使用ABFSS装载，并且它需要另一组参数用于

extra\u configs
