Wangda Tan commented on YARN-796: --------------------------------- Hi Allen, bq. I don't see dynamic labels generated from an admin provided script or class on the NM listed above If it means "set labels on yarn-site.xml in each NM, and NM will report such labels to RM". It should be a part of {{Distributed configuration (set labels in yarn-site.xml of NMs)}} in the TODO list. If it's not, could you please give me more details about what is "dynamic labels generated from an admin on the NM" in your thinking > Allow for (admin) labels on nodes and resource-requests > ------------------------------------------------------- > > Key: YARN-796 > URL: https://issues.apache.org/jira/browse/YARN-796 > Project: Hadoop YARN > Issue Type: Sub-task > Affects Versions: 2.4.1 > Reporter: Arun C Murthy > Assignee: Wangda Tan > Attachments: LabelBasedScheduling.pdf, > Node-labels-Requirements-Design-doc-V1.pdf, > Node-labels-Requirements-Design-doc-V2.pdf, YARN-796.node-label.demo.patch.1, > YARN-796.patch, YARN-796.patch4 > > > It will be useful for admins to specify labels for nodes.
