Access to Azure Blob Storage from U-SQL (credentials)

[valeri-ilyin]

I cannot find any information: how to register Azure Blob Storage credentials for getting access to a Blob Storage account from U-SQL.
Actually I'm getting the exception when I run the script:

Exception

E_STORE_USER_FAILURE: Secret not found for the specified user account Cosmos Path: wasb://data-lake-test@ccsdevus.blob.core.windows.net/test1/5cbf6597-9e23-420a-b186-eed5d771a493

Script (last step):

OUTPUT @group_by_masterid
TO "wasb://data-lake-test@ccsdevus.blob.core.windows.net/test1/master_id_inline.bin"
USING new V3Lake.Functions.DataNode.DataRecordOutputter();

I've found the solution: I need to add the Blob Storage account to the Data Lake account in Azure Portal. I'm closing the issue.
