我正在尝试使用 Key Vault 支持的机密范围将 Azure Blob 存储容器挂载到 Databricks 工作簿。
设置:
dbutils.secrets.get(scope = dbrick_secret_scope, key = dbrick_secret_name)
不会出错[REDACTED]
Databricks 中的单元格:
%python
dbrick_secret_scope = "dbricks_kv_dev"
dbrick_secret_name = "scrt-account-key"
storage_account_key = dbutils.secrets.get(scope = dbrick_secret_scope, key = dbrick_secret_name)
storage_container = 'abc-test'
storage_account = 'stgdev'
dbutils.fs.mount(
source = f'abfss://{storage_container}@{storage_account}.dfs.core.windows.net/',
mount_point = f'/mnt/{storage_account}',
extra_configs = {f'fs.azure.accountkey.{storage_account}.dfs.core.windows.net:{storage_account_key}'}
)
结果:
AttributeError: 'set' object has no attribute 'keys'
,mount_point
的 dbutils.fs.mount()
行以红色突出显示。AttributeError Traceback (most recent call last)

似乎与 extra_configs
参数有关,但我不确定是什么。谁能看到我错过了什么?
答案 0 :(得分:1)
在您的情况下真正的错误是您需要提供字典作为 extra_configs
参数,但是您提供的是集合:{{1}} - 发生这种情况是因为您没有正确的语法(两个 { {1}} 丢失)。正确的语法是:{f'fs.azure.accountkey.{storage_account}.dfs.core.windows.net:{storage_account_key}'}
但实际上您无法通过使用存储帐户密钥使用 '
协议进行挂载 - 仅支持使用 {f'fs.azure.accountkey.{storage_account}.dfs.core.windows.net':storage_account_key}
协议进行挂载。对于 abfss
,您必须使用服务主体,并提供其 ID 和机密,如下所示(请参阅 documentation):
wasbs
虽然理论上您可以使用 abfss
协议和存储密钥挂载 ADLS Gen2 存储,但不建议这样做,因为您可能会遇到问题(我个人认为)。另外,不建议使用存储密钥,最好使用共享访问签名 - 这样更安全。
