> In the past, we have a MemoryNodeLabelStore, mostly for user to try this
> feature without configuring where to store node labels on file system. It
> seems convenient for user to try this, but actually it causes some bad use
> experience. User may add/remove labels, and edit capacity-scheduler.xml.
> After RM restart, labels will gone, (we store it in mem). And RM cannot get
> started if we have some queue uses labels, and the labels don't exist in
> cluster.
> As what we discussed, we should have an explicitly way to let user specify if
> he/she wants this feature or not. If node label is disabled, any operations
> trying to modify/use node labels will throw exception.
