The cause of the crash on Linux was a inkompatible native libraries for the target OS. The native library was compiled with glibc and the OS with the crash use musl. It was not a bug in any of the libraries.

To solve the problem we bundle now a second version of the library. And differ with the follow code:

It looks like the dockerfile-maven-plugin uses a runtime based on x86 architecture and won't run on Apple M1 (Arm).
The plugin is now inactive so you should try something else, for example the fabric8-maven-plugin

You can't use connector compiled for Scala 2.11 with Spark 3.2.0 that is compiled with Scala 2.12. You need to use appropriate version - right now it's 3.1.0 with coordinates com.datastax.spark:spark-cassandra-connector_2.12:3.1.0

P.S. Please note that although basic functionality will work, more advanced functionality won't work until the SPARKC-670 is fixed (see this PR)
