[jira] [Updated] (STORM-1093) Launching Workers with resources
specified in resource-aware schedulers
[ https://issues.apache.org/jira/browse/STORM-1093?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Zhuo Liu updated STORM-1093:
----------------------------
Description:
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.
Such scheme can be used not only by RAS scheduler (STORM-893), but also be used by any customized scheduler for conducting mem/cpu resource aware scheduling.
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.
