我正在使用 azure databricks 创建一个简单的批处理，以将数据从 databricks 文件系统复制到另一个位置。
作为单元格中的命令，我通过了这个：
val df = spark.read.text("abfss://" + fileSystemName + "@" + storageAccountName + ".dfs.core.windows.net/fec78263-b86d-4531-ad9d-3139bf3aea31.txt")
源文件名是：fec78263-b86d-4531-ad9d-3139bf3aea31.txt
但是在运行 cmd 时，我收到此错误消息：
HEAD https://bassamsacc01.dfs.core.windows.net/bassamdatabricksfs01/fec78263-b86d-4531-ad9d-3139bf3aea31.txt?timeout=90

乍一看，访问托管在 azure 帐户存储中的文件系统似乎存在身份验证问题，但不知道如何添加适当的字符串。
如果问题有帮助，请投票。提前致谢。
