Copying multiple Files from Azure Blob to Lakehouse

[diveshwadhwa]

Hi Team,

I am encountering an issue while attempting to copy multiple files from an Azure Blob container to a Lakehouse using the wildcard file path and filepath option. The process is resulting in the following error message:

"ErrorCode=CopyCommandFailed,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException, Message=Copy operation failed with an internal error, Source=Microsoft.DataTransfer.ImportCommand.AzCopy'."

Any suggestions or guidance from the team would be greatly appreciated.

Thank you,

When I send individual files, the process completes successfully with no errors, and I can see the file in the Lakehouse as expected.

However, when I attempt to send an entire folder using both a wildcard and file path as the path, I receive an error. I have attached a picture for your reference that shows the setting for azure data factory pipeline.

Could you please advise on the correct method to send multiple files to the Lakehouse, particularly when using wildcards and file paths?

Thank you in advance for your assistance.

Best regards,

Divesh Wadhwa

@diveshwadhwa - I am not sure if this translates on the Pipeline side but when I do the wildcard paths in Notebooks (whether connecting to ADLS Gen2, Fabric Lakehouse, etc). I usually still had to provide the full wildcard path to get the files:

If my files weres stored in the following hierarchy:   Files/CRM/Sales/*.json  my wildcard path was   '/Files/*/*/*.json'

So in Pipelines you may need to make your path a dynamic parameter and set it to:   "/Excel/*/*/*.extension"

Hi @diveshwadhwa ,

Incorrect file paths, wildcard formatting, and insufficient permissions can all lead to this error, so see if the following documentation will help you.
