    @yegortokmakov in general, for one topology: 
    i:woker number
     worker number < cluster node number
     worker/per node
    ii:thread number
     this depends on your logic. for example, the parallelism of KafkaSpout 
should be equal to the number of partitions, in order to get a good performance.
    
    btw, I really recommend you to upgrade your storm to 1.0.1.

>
> In secure multitenant storm, topology workers are launched with permission of 
> the user that submitted the topology. This causes a problem with cgroups 
> since workers are launched with permissions of the topology user which does 
> not have permissions to modify cgroups storm is using
> Also, the clean up code is not trying to clean up cgroups of killed workers 
> if the initial attempt failed
