             Summary: ORC file footer cache should be bounded
                 Key: HIVE-10651
                 URL: https://issues.apache.org/jira/browse/HIVE-10651
             Project: Hive
          Issue Type: Bug
    Affects Versions: 1.3.0
            Reporter: Prasanth Jayachandran
            Assignee: Prasanth Jayachandran
            Priority: Minor


ORC's file footer cache is currently unbounded and is a soft reference cache. The cache size
got from config is used to set initial capacity. We should bound the cache from growing too
big and to get a predictable performance.
