I guess there may be a class conflict between your user jar and Flink lib. For the error: java.lang.NoClassDefFoundError, it may caused Exception happening when Initializing a class. I suggest you set the log level to DEBUG and send the client log here. Let’s look whether there are any new finding in the client log.
