I'm using Spark 3.0.1 with user provided Hadoop 3.2.0 and Scala 2.12.10 running on Kubernetes.
Everything works fine when reading a parquet file compressed as snappy, however when I try to read a parquet file compressed as zstd several tasks fails under the following error:
java.io.IOException: Decompression error: Version not supported

What I don't get is that those tasks succeed after a retry but not always and thus my jobs are failing frequently. As mentioned before if I use the same dataset compressed as snappy everything works.
I've also tried building Spark and Hadoop, changing the zstd-jni version, but the same behavior still happens.
Does anyone knows what might be happening?
Thanks!
As commented, I updated Spark (3.0.1) configuration with following property to permanently fix the issue in my case. The file path and configuration added are as follows:
$SPARK_HOME/conf/spark-defaults.conf
spark.shuffle.mapStatus.compression.codec lz4
