-----------------------------------
[~waywtdcc]
Flink's resource management is hierarchical.
JobMaster is not aware of TaskManager's resources, it only needs to declare the
required resources (per slot) to the ResourceManager. ResourceManager will
allocate resources (slots) from TaskManager to JobMaster.
I don't think it is a good idea to let the job know how many slots TaskManager
should have.
Could you describe the production scenario in detail? Does [Fine-Grained
Resource
Management|https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/finegrained_resource/]
satisfy it?
> Support taskmanager related parameters in session mode Support job
