Jungtaek Lim updated STORM-1093:
--------------------------------
Fix Version/s: 0.11.0
> 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
> Fix For: 0.11.0
>
>
> 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 a whole set of schemes 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
> (initially, the JVM heap size).
> This scheme can be used not only by RAS scheduler (STORM-893), but also by
> any customized scheduler for conducting mem/cpu/network resource
> specified-scheduling.
> In the future, the resources of memory, CPU and network can also be used by
> supervisor to launch a worker in a resource-segregated container, such as a
> CGroup or Docker, with isolated Memory/CPU/Network resources.
