> This JIRA includes APIs and storage implementations of node label manager,
> NodeLabelManager is an abstract class used to manage labels of nodes in the
> cluster, it has APIs to query/modify
> - Nodes according to given label
> - Labels according to given hostname
> - Add/remove labels
> - Set labels of nodes in the cluster
> - Persist/recover changes of labels/labels-on-nodes to/from storage
> And it has two implementations to store modifications
> - Memory based storage: It will not persist changes, so all labels will be
> lost when RM restart
> - FileSystem based storage: It will persist/recover to/from FileSystem (like
> HDFS), and all labels and labels-on-nodes will be recovered upon RM restart
