As part of S360 action to eliminate SPN secrets, we were asked to move to SPN+certificate / MSI/ User Assigned Managed Identity.
We tried connecting using a custom Active directory (AD) token rather than a client secret through databricks. PEM certificate was used to generate the custom AD token through Java code. We tried to pass the AD token via OAUTH2 method setting below spark configuration.
%scala
// Set up Spark configurations for ADLS Gen2 access with Azure AD token
spark.conf.set("fs.azure.account.auth.type.<Your storage Account>.dfs.core.windows.net", "OAuth")
spark.conf.set("fs.azure.account.oauth.provider.type.<Your storage Account>.dfs.core.windows.net", "org.apache.hadoop.fs.azurebfs.oauth2.ClientCredsTokenProvider")
spark.conf.set("fs.azure.account.oauth2.client.id.<Your storage Account>.dfs.core.windows.net", "clientid")
spark.conf.set("fs.azure.account.oauth2.client.secret.<Your storage Account>.dfs.core.windows.net", "")
spark.conf.set("fs.azure.account.oauth2.client.endpoint.<Your storage Account>.dfs.core.windows.net",https://login.microsoftonline.com/<Tenanant-Id>/oauth2/v2.0/token)
spark.conf.set("fs.azure.account.oauth2.access.token.provider", access_token)
To link to an ADLS Gen 2 storage account and access files, we are encountering the following issue.
