Subject [jira] [Created] (HIVE-4709) Caching OIs in OIFactory should be disabled
Date Tue, 11 Jun 2013 04:17:20 GMT
Navis created HIVE-4709:
---------------------------

             Summary: Caching OIs in OIFactory should be disabled
                 Key: HIVE-4709
                 URL: https://issues.apache.org/jira/browse/HIVE-4709
             Project: Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Navis
            Assignee: Navis


OIFactory has various caches and most of them are accessed by key containing OIs. But OIs
are not forced to implement hashCode/equals and that is resulted to some kind of memory leakage.


Considering the price of calculating/accessing hashmap, just removing those caches are better
solution, IMHO.
