Subject [jira] [Commented] (YARN-796) Allow for (admin) labels on nodes and resource-requests
Date Wed, 10 Sep 2014 03:51:33 GMT

Wangda Tan commented on YARN-796:
---------------------------------

Hi [~cwelch] and [~aw],
I agree with #3 as well, since the original starting point is to avoid case-typo from users.
But refer to other existing configs of YARN, like queue name of CS, different case of queue
name means different queue. I prefer to drop the requirement if there's no strong opinion
to do that.

Thanks,
Wangda

> 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.
