             Summary: Implement a memory manager for ORC
                 Key: HIVE-4248
                 URL: https://issues.apache.org/jira/browse/HIVE-4248
             Project: Hive
          Issue Type: New Feature
          Components: Serializers/Deserializers
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


With the large default stripe size (256MB) and dynamic partitions, it is quite 
easy for users to run out of memory when writing ORC files. We probably need a 
solution that keeps track of the total number of concurrent ORC writers and 
divides the available heap space between them.
