Description

We started implementing storm workers in docker containers and limiting the max CPU to be as specified by the worker.  We found that although a small amount of CPU may run the worker code successfully, it prevents starting the worker within the worker startup timeout. 

 

It would be nice to have a minimum cpu setting that forces a minimum amount of cpu to be used for the workers to allow them to come up.
