Wangda Tan created YARN-3354:
Summary: Container should contains node-labels asked by original
Project: Hadoop YARN
Issue Type: Sub-task
Components: api, capacityscheduler, nodemanager, resourcemanager
Reporter: Wangda Tan
Assignee: Wangda Tan
We proposed non-exclusive node labels in YARN-3214, makes non-labeled resource
requests can be allocated on labeled nodes which has idle resources.
To make preemption work, we need know an allocated container's original node
label: when labeled resource requests comes back, we need kill non-labeled
containers running on labeled nodes.
This requires add node-labels in Container, and also, NM need store this
information and send back to RM when RM restart to recover original container.
