Hi @Alberto_Umana , I am facing the same issue. It works when i try to read the xml file as text using spark.read.text(), but fails when I try to read it in xml format. I'm authenticating using spn and the config is correct as i'm able to read json files from the same folder and also the xml file in text as mentioned.

Also it works if i use the mounted path to the file and not when i use the abfss path.

Could it be an issue with the spark-xml library not being able to work directly with abfss? 

I have the following installed in my cluster: com.databricks:spark-xml_2.12:0.15.0
