Stephan Ewen commented on FLINK-3162:
-------------------------------------

I think this is reasonable for standalone setups.

Figuring out what would be a good number of cores per container to request in YARN is probably a separate issue by itself.

> The number of TaskManager slots is currently only configurable by explicitly setting {{taskmanager.numberOfTaskSlots}}. Make this configurable by a ratio of the number of available processors (for example, "2", for hyperthreading). This can work in the same way as {{taskmanager.memory.size}} and {{taskmanager.memory.fraction}}.
