Roughly from the logs you can see the cause of conflict package, but it really is not very good investigation.
Try 1:
According to the instructions of users, flink-conf.xml modified configuration items as follows: classloader.resolve-order
The results are still being given the wrong without any change.
classloader.resolve-order: parent-first
Try 2:
The Internet to find a blog, in fact, and this relationship is not very large, according to which said attempts to modify the maven dependency,
After a total increase after following these dependencies, the code submitted to the cluster was able to run correctly.
