Sandy Ryza commented on YARN-796:
---------------------------------
Makes a lot of sense to me. One nit:
bq. Each scheduler (CS, FS) can pick how they want labels specified in their
configs
Correct me if I'm misunderstanding what you mean here, but currently neither
scheduler has node-specific stuff in its configuration. Updating the scheduler
config when a node is added or removed from the cluster seems cumbersome.
Should labels not be included in the NodeManager configuration like Resources
are?
> Allow for (admin) labels on nodes and resource-requests

> It will be useful for admins to specify labels for nodes. Examples of labels
> are OS, processor architecture etc.
> We should expose these labels and allow applications to specify labels on
> resource-requests.
> Obviously we need to support admin operations on adding/removing node labels.
