> 1) Add yarn.node-labels.manager-class, by default it's will not store anything to file
system
> 2) Use above at least in some places: RMNodeLabelsManager, RMAdminCLI. Convert {{DummyNodeLabelsManager}}
into a {{MemoryNodeLabelsManager}}
> 3) Document that RM configs and client configs for yarn.node-labels.manager-class should
match
> 4) fs-store.uri -> fs-store.root-dir
> 5) Similarly FS_NODE_LABELS_STORE_URI
> 6) For default value of fs-store.uri, put it in /tmp. But creaat /tmp/hadoop-yarn-$\{user\}/node-labels
