> Hive 0.6.0 we upgraded the version of DataNucleus from 1.0 to 2.0, which
> changed some of the defaults for how field names get mapped to datastore
> identifiers. This was problem was resolved in HIVE-1435 by setting
> datanucleus.identifierFactory=datanucleus in hive-default.xml
> However, this property definition was not added to HiveConf. This can result
> in schema corruption if the user upgrades from Hive 0.5.0 to 0.6.0 or 0.7.0
> and retains the Hive 0.5.0 version hive-default.xml on their classpath.
