Xuefu Zhang commented on HIVE-4900:
-----------------------------------

[~appodictic] Mysql 0.10 schema file doesn't create SORT_ORDER either. I think 
MOrder<->SORT_ORDER definition there is redundant, it can be probably removed 
safely. Also, it's declared as embedded-only=true, so there should be no 
standalone objects mapped to that table. I didn't spend much time on this as my 
effort is about HIVE-3632. I can create a different JIRA for that. I modified 
the column name just in order to be consistent with MOrder O-R mapping later 
defined in SDS, which I could have spared.

> There are several errors in DataNucleus O-R mapping file, package.jdo, which 
> are not complained by the existing DN version. These errors may be subject to 
> future DN complaint (as experienced in HIVE-3632 and HIVE-2084). However, it 
> is still better if we fix these errors as it also creates some confusion in 
> the community.
