    Description

      YARN service placement constraint does not work with node label nor node attributes. Example of placement constraints:

       
            "placement_policy": {
              "constraints": [
                {
                  "type": "AFFINITY",
                  "scope": "NODE",
                  "node_attributes": {
                    "label":["genfile"]
                  },
                  "target_tags": [
                    "ping"
                  ] 
                }
              ]
            },
      

      Node attribute added:

       ./bin/yarn nodeattributes -add "host-3.example.com:label=genfile" 

      Scheduling activities shows:

       <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>
