创建范围以从Databricks访问Azure Datalake Gen2时发生属性错误

Question

我试图使用示波器进行设置，但遇到了一些问题。任何帮助将不胜感激。

我在Databricks CLI中运行了以下命令

databricks secrets create-scope --scope dnb-dlg2-dbrcks-scp-stg
databricks secrets put --scope dnb-dlg2-dbrcks-scp-stg --key SPID --string-value "XXXXXXXXXXXXXXXXXX"
databricks secrets put --scope dnb-dlg2-dbrcks-scp-stg --key SPKey --string-value "XXXXXXXXXXXXXXX”
databricks secrets put --scope dnb-dlg2-dbrcks-scp-stg --key DirectoryID --string-value "XXXXXXXXXX"

成功创建了范围。然后我尝试在笔记本中运行以下内容

#Gather Relevant Keys from our scope

ServicePrincipalId=dbutils.secret.get(scope="dnb-dlg2-dbrcks-scp-stg",key="SPID")
ServicePrincipalKey=dbutils.secret.get(scope="dnb-dlg2-dbrcks-scp-stg",key="SPKey")
DirectoryID=dbutils.secret.get(scope="dnb-dlg2-dbrcks-scp-stg",key="DirectoryID")

#Combine DirectoryID into full string
Directory="https://login.microsoftonline.com/{}/oauth2/token".format(DirectoryID)

#Create configurations for our connections
configs = {"fs.azure.account.auth.type": "OAuth",
           "fs.azure.account.oauth.provider.type": "org.apache.hadoop.fs.azurebfs.oauth2.ClientCredsTokenProvider",
           "fs.azure.account.oauth2.client.id" : ServicePrincipalId,
           "fs.azure.account.oauth2.client.secret":  ServicePrincipalKey,
           "fs.azure.account.oauth2.client.endpoint": Directory}
# "fs.azure.account.oauth2.client.secret" -> dbutils.secrets.get("dnb-dbrk-scrt-scp-stg", key = "dnb-data-bricks-kv-stg"),

# Mount the Data Lake onto DBFS at the /mnt/ location

dbutils.fs.mount(
  source = "abfss://datastore@dbstgstoraccgen2.dfs.core.windows.net/",
  mount_point = "/mnt/datastore5",
  extra_configs = configs)

这时我出错了，请参考下图

Answer 1

您的代码中的拼写错误小：“ 秘密”应为“ 秘密”。

错误：

TypeConverter

将“ secret.get ”替换为“ secrets.get ”

ServicePrincipalId=dbutils.secret.get(scope="dnb-dlg2-dbrcks-scp-stg",key="SPID")
ServicePrincipalKey=dbutils.secret.get(scope="dnb-dlg2-dbrcks-scp-stg",key="SPKey")
DirectoryID=dbutils.secret.get(scope="dnb-dlg2-dbrcks-scp-stg",key="DirectoryID")

希望这会有所帮助。如果您还有其他疑问，请告诉我们。
