             Summary: make direct SQL work with identityFactory datanucleus2
                 Key: HIVE-7285
                 URL: https://issues.apache.org/jira/browse/HIVE-7285
             Project: Hive
          Issue Type: Bug
          Components: Metastore
            Reporter: Sergey Shelukhin


Apparently, some people set identityFactory to datanucleus2 for some reason. When that is
used, some column names in DN schema are different; the most prominent is INTEGER_IDX changing
to IDX. That causes direct SQL to break; queries still work via ORM, but become slow with
many partitions. It seems it's easier to just support both, rather than try to enforce some
standard or have people convert databases.
