Xuefu Zhang commented on HIVE-4900:
-----------------------------------
That's correct. I don't think any upgrade is needed for the purpose of DN
upgrade and HIVE-4900.2.patch is needed for that.
As mentioned in 2084, there needs an upgrade for "comment" column for table
TYPE_FIELDS and COLUMNS_V2, which needs to be brought up from current 256 to
4000. I'll create a separate JIRA for that, as it's irrelevant to DN upgrade.
> Fix the mismatched column names in package.jdo

> 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.
