>
> Currently, flink cli can't figure out JobManager RPC location for
> Flink-on-YARN clusters. Therefore, list, savepoint, cancel and stop
> subcommands are hard to invoke if you only know the YARN application ID. As
> an improvement, I suggest adding a -yid <yarnApplicationId> option to the
> mentioned subcommands that can be used together with -m yarn-cluster. Flink
> cli would then retrieve JobManager RPC location from YARN ResourceManager.
