我使用azuredatabricks创建一个简单的批处理，将数据从databricks文件系统复制到另一个位置。
作为一个牢房里的命令，我传递了这个：

val df = spark.read.text("abfss://" + fileSystemName + "@" + storageAccountName + ".dfs.core.windows.net/fec78263-b86d-4531-ad9d-3139bf3aea31.txt")

其中源文件名为： fec78263-b86d-4531-ad9d-3139bf3aea31.txt 但在运行cmd时，我收到以下错误消息：

HEAD https://bassamsacc01.dfs.core.windows.net/bassamdatabricksfs01/fec78263-b86d-4531-ad9d-3139bf3aea31.txt?timeout=90

乍一看，访问azure帐户存储中托管的文件系统时似乎存在身份验证问题，但不知道如何添加适当的字符串。
