Permission error loading dataframe from azure unity catalog to GCS bucket

[kiko_roy]

I am creating a data frame by reading a table's data residing in Azure backed unity catalog. I need to write the df or file to GCS bucket. I have configured the spark cluster config using the GCP service account json values.

on running : 

df1.write.format("parquet").save("gs://dev-XXXX-analyt-XXXXXXXX") getting error :
Insufficient privileges: User does not have permission SELECT on any file.. what could be the reason or resolution. Need help

Hi, is there any terraform resource to apply this GRANT or this have to be done always manually?

Hi @ruloweb , apart from granting access manually on any File, one way that resolved the issue for me was to use a cluster with single user.
