bc Wong commented on YARN-796: ------------------------------ Having the NMs specify their own labels is probably better from an administrative point of view. It's harder for the labels to get out of sync. Each node can have a "discovery script" that updates its labels, which feeds into the NM. So an admin can take a bunch of nodes out for upgrade, and put them back in without having to carefully reconfigure any central mapping file. > 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 > Reporter: Arun C Murthy > Assignee: Wangda Tan > Attachments: YARN-796.patch > > > It will be useful for admins to specify labels for nodes.
