             Summary: Launching Workers with resources specified in resource-aware schedulers
                 Key: STORM-1093
                 URL: https://issues.apache.org/jira/browse/STORM-1093
             Project: Apache Storm
          Issue Type: Story
          Components: storm-core
            Reporter: Zhuo Liu
            Assignee: Zhuo Liu


Currently, we have Resource Aware Scheduler (STORM-894) in nimbus, which can allocate different types of resource (CPU, onheap-memory, offheap-memory) to the workers assigned to each topology's tasks.

However, such resources are not visible to the supervisor, therefore, supervisor will still launch workers with fixed amount of heap size memory (e.g., -Xmx=768M). 

Therefore, we need to a whole set of scheme that allow nimbus to put different types of resources to each worker slot, then push the resources with assignment to ZooKeepers; also, at the supervisor side, such resources in each worker slot should be used by supervisor for launching a worker's JVM.

In the future, the resources of CPU and network can also be used by supervisor to launch a worker in a resource-segregated container, such as a CGroup or Docker.
