    Description

      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.
