Gen 2 Dataflow has started Failing - MashupException.Error: The specified path already exists.
Hi higgy7
Based on the error message you provided, the problem appears to be related to a "Mixed Exception Data Source Error".
The error message indicates that there may be a conflict in the paths used in the data streams.
Make sure that the paths specified for each data stream to store data in the lake are unique. If there is an overlap, this may result in the above error.
Since you mentioned that a second data stream was created at the start of the failure, it is worth checking whether there are any conflicts or resource contention issues with these two data streams.
It is possible that both data streams are running in the same workspace and targeting the same lake.

Hi Nono,
So this is what i am trying to understand about Lakehouses. The 2 dataflows will be pulling the same data but i was appending them into 2 different tables in the same Lakehouse. Is the issue that a Lakehouse isn't actually storing the data in tables in the traditional sense? I would assume this is what the issue is but I want to get an understanding of how the storage works etc. See images showing the same data from 2 dataflows appending to 2 different tables but in the same lakehouse
