--------------------------------------
Summary: ClusterNodeTracker: add method to get list of nodes
matching a specific resourceName
Key: YARN-5181
URL: https://issues.apache.org/jira/browse/YARN-5181
Project: Hadoop YARN
Issue Type: Improvement
Components: scheduler
Affects Versions: 2.8.0
Reporter: Karthik Kambatla
Assignee: Karthik Kambatla
ClusterNodeTracker should have a method to return the list of nodes matching a
particular resourceName. This is so we could identify what all nodes a
particular ResourceRequest is interested in, which in turn is useful in
YARN-5139 (global scheduler) and YARN-4752 (FairScheduler preemption overhaul).
