The easiest way to fix the problem is to create the objects needed for the encryption directly within the executor's VM by moving the code block into the udf's closure: val encryptUDF = udf ( (uid : String) => { val Algorithm = "AES/CBC/PKCS5Padding" val Key = new SecretKeySpec ...1 Answer. I will suggest you to read something about serializing non static inner classes in java. you are creating a non static inner class here in your map which is not serialisable even if you mark that serialisable. you have to make it static first.
