【问题描述】：
我希望删除 Azure Data Lake 中的一个文件夹。该文件夹包含子文件夹和文件。这是我尝试过的：
DataLakeServiceClient dataLakeServiceClient = new DataLakeServiceClientBuilder()
.endpoint("https://aiops3e1fb6dcf0fef5.dfs.core.windows.net")
.credential(new DefaultAzureCredentialBuilder().build())
.buildClient();
delete(dataLakeServiceClient);
DataLakeFileSystemClient core = dataLakeServiceClient.getFileSystemClient("core");
String toDelete = "2022/01/25/09/30/";
System.out.println(core.getFileClient(toDelete).exists()); // prints true
DataLakeDirectoryClient directoryClient = core.getDirectoryClient(toDelete);
directoryClient.deleteWithResponse(true, null, null, Context.NONE);
它给了我以下错误：
线程“main”中的异常 com.azure.storage.file.datalake.models.DataLakeStorageException： 状态码 400, "{"error":{"code":"InvalidUri","message":"请求 URI 是
