Xuefu Zhang commented on HIVE-5218:
-----------------------------------
I'd just like to point out that passing unit tests might not be enough, as
these tests are against embedded derby. There is a way to hack into the build
such that tests are running against other DBs such as MySQL. Also, I'd think
manual testing on other aspects might be necessary, such as existing metastore
from previous release(s), upgrade path, etc.

> HIVE-3632 upgraded datanucleus version to 3.2.x, however, this version of
> datanucleus doesn't work with SQLServer as the metastore. The problem is that
> datanucleus tries to use fully qualified object name to find a table in the
> database but couldn't find it.
> If I downgrade the version to HIVE-2084, SQLServer works fine.
> It could be a bug in datanucleus.
> This is the detailed exception I'm getting when using datanucleus 3.2.x with
> SQL Server:
