Hi,

I am redesigning the scheduler of the JobManager to place tasks of a job across TaskManagers accroding to a scheduling policy.

I am reading the Flip-6 proposal and found that the common case is "one TaskManager launchs one slot", and "one Flink cluster serves one job". But I did not find how many TaskManagers to launch in a computing node. Is there any common practice for this ?
