Varun Saxena commented on YARN-3003:
------------------------------------
Thanks [~leftnoteasy] for your input. Yes, its about getting labels to nodes.
Separating it out into 2 APIs' is more cleaner and less confusing to the user.
Basically wanted your input on whether we need this new API or not.
I had a similar idea in mind regarding how to fix this issue. Will look at
YARN-2943 as well as [~Naganarasimha] suggested.
Thanks.

> Currently YarnClient#getNodeToLabels() returns the mapping from NodeId to set
> of labels associated with the node.
> Client (such as Slider) may be interested in label to node mapping - given
> label, return the nodes with this label.
