-------------------------------------
[~abarbulescu] We have a built-in AVRO data source implementation since
SPARK-24768(2.4.0). Could you try to remove {{--jars Spark-Avro 2.4.0}} and
load avro by {{spark.read.format("avro").load("/path/to/avro")}}
> Provider org.apache.spark.sql.avro.AvroFileFormat could not be instantiated

> We get the exact same error when trying to read a local .avro file instead of
> from Cassandra.
> Up to now we included the .jar file for Spark-Avro using the spark-submit
> --jars option. The version of Spark-Avro that we used, and worked with Spark
> 2.4.1, was Spark-Avro 2.4.0.
> In an attempt to fix this problem we tried updating the .jar file version. We
> also tried using the --packages option, with different version combinations,
> but none of these solutions worked. The same error shows up every time.
> When rolling back to Spark 2.4.1 with the exact same setup and code, the
> error doesn't show up and everything works fine.
> Any ideas on what could be causing this?
