Lohit Vijayarenu commented on YARN-796:
---------------------------------------
As [~tucu00] mentioned, label sounds closely related to affinity and should be
treated less off a resource. It becomes closely related to resources when it
comes to exposing them on scheduler queues and exposing that to users who wish
to schedule their jobs on certain set of labeled nodes. This is definitely very
useful feature to have. Looking forward for design document.
> 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.
