             Summary: hive incremental load going OOM while adding load task to the leaf nodes of the DAG
                 Key: HIVE-21700
                 URL: https://issues.apache.org/jira/browse/HIVE-21700
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 4.0.0
            Reporter: mahesh kumar behera
            Assignee: mahesh kumar behera
             Fix For: 4.0.0


While listing thee child nodes to check for leaf node, we need to filter out tasks which are already added to the children list. If a task is added multiple time to the children list then it may cause the list to grow exponentially.
