Namit Jain commented on HIVE-1108:
----------------------------------

65 		 private ArrayList<Task<? extends Serializable>> rootTasks; 	
				66 		private FetchTask fetchTask; 	
				67 		private HashSet<ReadEntity> inputs; 	
				68 		private HashSet<WriteEntity> outputs; 	
				69 			
				70 		private HashMap<String, String> idToTableNameMap;



Do you think instead of adding the following fields in QueryPlan, you might create a new serializable structure and share it between SemanticAnalyzer and QueryPlan ?
