Azure Dataware House Destination error log


I am getting this error when trying to connect to our Azure Dataware House Destination

External file access failed due to internal error: ‘Error occurred while accessing HDFS: Java exception raised on call to HdfsBridge_IsDirExist. Java exception message:
HdfsBridge::isDirExist - Unexpected error encountered checking whether directory exists or not: StorageException: Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.’

We verified that:

  • Blob URI is valid (tested from outside)

  • Database user has access to database (tested from outside)

  • Database user has CONTROL

Setup has been working for over 30 days, suddenly failing from Thu 20.feb an onwards

any clues?

Philip, my colleagues on our support team tell me they’re working with you on this issue. I hope you get it squared away soon.
