[jira] [Created] (HIVE-5491) Some lazy DeferredObjects inspectors are "fat"

Edward Capriolo created HIVE-5491:
-------------------------------------

             Summary: Some lazy DeferredObjects inspectors are "fat"
                 Key: HIVE-5491
                 URL: https://issues.apache.org/jira/browse/HIVE-5491
             Project: Hive
          Issue Type: Improvement
            Reporter: Edward Capriolo
            Priority: Minor


I was looking at some of the implementations of DeferredObject. I found that some carry two extra-properties:
boolean eager;
boolean eval;

Where eval is used to track if the obj is initiated. My thinking is that these extra properties make the objects "fat" and if removed it allows us to fit more lazy objects in the same memory.
