In this jira, we will only > contain changes in scheduler. > The flow to update node's resource and awareness in resource scheduling is: > 1. Resource update is through admin API to RM and take effect on RMNodeImpl. > 2. When next NM heartbeat for updating status comes, the RMNode's resource > change will be aware and the delta resource is added to schedulerNode's > availableResource before actual scheduling happens. > 3. Scheduler do resource allocation according to new availableResource in > SchedulerNode. > For more design details, please refer proposal and discussions in parent > JIRA: YARN-291. -- This message was sent by Atlassian JIRA (v6.1#6144)
