> Evaluate running Ambari Server Upgrade via code rather than DDL/DML.
> The upgrade procedure has become a mammoth exercise and very error prone. We
> need to make sure we can do it via java code (which can be unit tested).
> If possible:
> ambari-server upgrade should do any database changes via java code which can
> use eclipse link to make any changes.
> This change allows devs to be flexible about what we can add in upgrade and
> also unit test those.
