Wangda Tan commented on YARN-796:
---------------------------------
[~rkannan82],
Did you mean capacity scheduler? Since currently fair scheduler support node
label is still in open state (YARN-2497), or you wanna do it along with the
effort of YARN-2497. I can understand your proposal, it is a valid enhancement
for sure, but a trade-off is we need add more complexities in scheduling logic
(we already have complex scheduler implementation in both fair/capacity
scheduler), we need figure out if it is necessary.
If you plan to do it, I can help with implementation discussion and review.
Thanks,
Wandga

> 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.
