Hi Leon, If you are using application mode through Flink on YARN, the codes in YARNApplicationITCase may be helpful, which has similar function calls with CliFrontend but may be more straightforward.
Side notes: in my own experience of using Flink, it is not a very good idea to run a flink jar using java codes through application mode. If you are using session modes, there could be some RESTful interfaces which makes life much easier. But when using application mode, the cluster is launched after running commands like `flink run-application -t yarn-application ….` so REST services are not initially available. As a result, you have to fight with some deployment details like setting environment variables, making classloaders work correctly and so on. All details shaded by flink have to be handled by hand.

Ideally I'd like my java code to just call an API to achieve this. Does flink provide a rest API to support this? I don't seem to find any documentation or code on that. If I need to build this on my own, is there any example I can follow? Should I just follow how CliFrontend.java does ? (I believe the command line calls this internally)? Or is there any other better examples? Thanks Leon
