> YARN service placement constraint does not work with node label nor node
> attributes. Example of placement constraints:
> {code}
> "placement_policy": {
> "constraints": [
> {
> "type": "AFFINITY",
> "scope": "NODE",
> "node_attributes": {
> "label":["genfile"]
> },
> "target_tags": [
> "ping"
> ]
> }
> ]
> },
> {code}
> Node attribute added:
> {code} ./bin/yarn nodeattributes -add "host-3.example.com:label=genfile"
> {code}
> Scheduling activities shows:
> {code} <diagnostic> Node does not match partition or placement constraints,
> unsatisfied PC expression="in,node,ping", target-type=ALLOCATION_TAG
> </diagnostic>
> <count>1</count>
> <nodeIds>host-3.example.com:45454</nodeIds>{code}
