             Summary: Replace all occurences of new Long, Boolean, Double etc 
with the corresponding .valueOf
                 Key: HIVE-21297
                 URL: https://issues.apache.org/jira/browse/HIVE-21297
             Project: Hive
          Issue Type: Improvement
            Reporter: Ivan Suller
            Assignee: Ivan Suller
             Fix For: 4.0.0


Creating Integer objects with new Integer(...) creates a new object, while 
Integer.valueOf(...) can be cached (and is actually cached in most if not all 
JVMs) thus reducing GC overhead.
