Max commented on YARN-796:
--------------------------
I would like to add user case for this Feature:
We are developing platform which can setup different tools for execution on
YARN.
In our industry exists tools which require a specific hardware such as GPU
(from Nvidia) and/or FPGA. These tools are not too often executed.
Setup hardware (GPU/FPGA) on each node will be too expensive and unreasonable
due to rare usage.
The only optimal solution will be to use tags.
> 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.
