我也遇到过类似的问题。正如 James 上面提到的,这是由于使用了仅适用于 ADLS gen2 的 API。如果您要设置新的存储帐户,则可以直接使用 Gen2 存储创建帐户,如上所述: https://learn.microsoft.com/en-us/azure/storage/blobs/create-data-lake-storage-account#enable-the-hierarchical-namespace
如果您已经设置了帐户,则也可以将其升级以使用 ADLS gen2。唯一需要注意的是,在升级过程中此帐户中的所有容器都将无法访问,包括 UI 访问以及您可能附加到这些容器的任何其他 Hook 。以下是如何继续升级。
非常感谢您的帮助 @James
