---------------------------------

             Summary: Cluster metrics is inaccurate when placement constraint is enabled
                 Key: YARN-7784
                 URL: https://issues.apache.org/jira/browse/YARN-7784
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: metrics, RM
            Reporter: Weiwei Yang


Reproducing steps
 # Setup a cluster and sets {{yarn.resourcemanager.placement-constraints.enabled}} to true
 # Submit a DS job with placement constraint, such as {{-placement_spec foo=2,NOTIN,NODE,foo}}
 # Check cluster metrics from http://<RM_ADDRESS>/cluster/apps

when job is running, {{Containers Running}}, {{Memory Used}} and {{VCore Used}} were not updated (except AM), metrics from containers allocated by the PlacementProcessor were not accumulated to the cluster metrics; however when job is done, the resource were deducted. Then UI displays like following:
 * Containers Running: -2
 * Memory Used: -400
 * VCores Used: -2

Looks like {{AppSchedulingInfo#updateMetricsForAllocatedContainer}} was not called when allocating a container.
