How to use azure data lake store gen1 source in dataflow?

Hi everyone,

 

I have a CSV file stored in azure data lake store gen1 which I would like to use in a Power BI service dataflow.

The query to the CSV file works fine in Power BI desktop.

 

I've tried to do following steps:

- Create a dataflow

- Define a new entity

- Use "Emtpy query" as data source

- Copy over the first line in power query from desktop into online editor:

let
Source = DataLake.Contents("adl://xx.azuredatalakestore.net/xx...csv")
in
Source

 

- Then the online editor request to configure the connection, I start the dialog

- I select "organizational account" (the dialog shows "You're logged in")

 

Observations:
- Online editor shows a warning "query contains 1 errors" on bottom left, but not the issue. the editor still request to configure the connection.

- The connection dialog shows a URI 'Datalake: https://xx.azuredatalakestore.net/xx...csv' instead of the URI used in power query 'DataLake.Contents("adl://xx.azuredatalakestore.net/xx...csv")'

- I've also tried to "login with another user", but no change in result.

 

--> Does anybody know how to use azure data lake store gen1 in dataflows?
 

Best regards,

Thomas

Hi Jay,

 

the linked document only mentions how to do this for Gen 2 data lake. My data lake if of Gen One.

I also tried out providing my Gen1 URI to Gen2 connector but this didn't worked.

 

So this does not solve my issue.

 

Best regards,

Thomas

 

 

Hi Thomas,

 

Did you ever find a solution for this? I'm running into the same problem.

 

Thanks!

Hi,

 

no. We've moved to Azure SQL Database as data source for Power BI reports. CSV files also have generally very low performance.

 

Best regards,

Thomas
