Varun Saxena commented on YARN-3075:
------------------------------------

bq. When a node/host has no label, it belongs to a special NodeLabel with key = 
CommonNodeLabelsManager.NO_LABEL. This is necessary because node without label 
can be considered as a "partition" as well. We need support it here (even if 
getLabelsToNode not return it now.)
bq. For scheduling purpose, since we already have getResourceByLabel supports 
No_LABEL case. I think it's fine to move it to a separated JIRA.
You want me to add node to the entry of NO_LABEL once activated ? Any use case 
of this label to node mapping elsewhere ?
