Loading

I'm trying to load a bunch of files that have the same schema (all the files are a dump from the same table in SAS). The expected result is a dataframe with the concatenation of all the sas files.

Apache Spark 3.1.2
Scala 2.12
com.epam:parso:2.0.14
saurfang:spark-sas7bdat:3.0.0-s_2.12

Code

%scala
spark.read.format("com.github.saurfang.sas.spark").option("inferSchema", "true").load("dbfs:/mnt/tables/")

And I get this error when I run the command

FileNotFoundException: /tables is a directory not a file.

Can't you loop through all the files and load them individually?

Yes, that was the workaround that I used but I was wondering if was possible to load all of them at the same time.
