Hyukjin Kwon commented on SPARK-46032: -------------------------------------- Are executors using the same versions too? The error is most likely from a different version of JDK and Scala version. I can't reproduce them locally so sharing fulll specification of the server and the client would be very helpful. > connect: cannot assign instance of java.lang.invoke.SerializedLambda to field >
