Hi Peter, Thanks a lot for starting this discussion. I think this is a very useful feature.
Not only for Yarn, i am focused on flink on Kubernetes integration and come across the same problem. I do not want the job graph generated on client side. Instead, the user jars are built in a user-defined image. When the job manager launched, we just need to generate the job graph based on local user jars. I have some small suggestion about this. 1. `ProgramJobGraphRetriever` is very similar to `ClasspathJobGraphRetriever`, the differences are the former needs `ProgramMetadata` and the latter needs some arguments. Is it possible to have an unified `JobGraphRetriever` to support both? 2. Is it possible to not use a local user jar to start a per-job cluster? In your case, the user jars has existed on hdfs already and we do need to download the jars to deployer service. Currently, we always need a local user jar to start a flink cluster. It is be great if we could support remote user jars. >> In the implementation, we assume users package flink-clients, flink-optimizer, flink-table together within the job jar. Otherwise, the job graph generation within JobClusterEntryPoint will fail. 3. What do you mean about the package? Do users need to compile their jars inlcuding flink-clients, flink-optimizer, flink-table codes?
