It ends up to be a release gap between the build env libs and the
runtime.nothing else.Am updating everything to the latest+greatest.With the
latest Flink, and the current (old) code the Maven reports:[ERROR] symbol:
class FlinkKafkaConsumer08
Meaning it needs to be replaced with the latest consumer object.
Any suggestions on modernizing the FlinkKafkaConsumer
implementation?Thanks+regards

Hi, amir, I think you could check the log of job manager to make sure that
job manager [192.168.56.101:6123 <http://flink@192.168.56.101:6123/>] is
running well firstly, you may get what is wrong in the log.
