Wangda Tan created YARN-4026: -------------------------------- Summary: FiCaSchedulerApp: Revisit ContainerAllocator interface design Key: YARN-4026 URL: https://issues.apache.org/jira/browse/YARN-4026 Project: Hadoop YARN Issue Type: Bug Reporter: Wangda Tan Assignee: Wangda Tan
After YARN-3983, we have an extensible ContainerAllocator which can be used by FiCaSchedulerApp to decide how to allocate resources. While working on YARN-1651 (allocate resource to increase container), I found existing logic: - ContainerAllocator decides what to allocate for a given node and priority, it's not flexible enough: To support different kinds of resource allocation, for example, priority as weight / skip priority or not, etc. It's better to let ContainerAllocator to choose how to order resource request according to priorities. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
