             Summary: Store and update allocation tags in the Placement Constraint Manager
                 Key: YARN-6597
                 URL: https://issues.apache.org/jira/browse/YARN-6597
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Konstantinos Karanasos


Each allocation can have a set of allocation tags associated to it.
For example, an allocation can be marked as hbase, hbase-master, spark, etc.
These allocation-tags are active in the cluster only while that container is active (from the moment it gets allocated until the moment it finishes its execution).
This JIRA is responsible for storing and updating in the {{PlacementConstraintManager}} the active allocation tags in the cluster.
