Wangda Tan commented on YARN-796:
---------------------------------
[~jameszhouyi],
bq. Illegal capacity of 1.0 for children of queue root for label=y
You should set root.accessible-node-labels.y.capacity = 100.
And Node Labels UI may not be existed in 2.6.
I would suggest you send more question about usages of YARN components to
hadoop users mail list. JIRA is majorly for dev discussions.
Thanks,

> 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.
