Wenchen Fan commented on SPARK-18050:
-------------------------------------
ah, it's not throwing an exception, but logging an error message. When we try
to create the default database, we ask hive to do nothing if it already exists.
However, Hive will log an error message instead of doing nothing. This should
be fine and you can just ignore it.
> spark 2.0.1 enable hive throw AlreadyExistsException(message:Database default
> already exists)
