> The metastore's validation error message when attempting to rename a table to a non-existent
database is wrong.  For instance, attempting to alter table 'db.table' to 'non_existent_database.table'
results in the Thrift error:
> {{TException - service has thrown: InvalidOperationException(message=Unable to change
partition or table. Database db does not exist Check metastore logs for detailed stack.non_existent_database)}}
> I believe the offending line of code is [here|],
notice that {{dbname}} is used in the message, not {{newDbName}}.  I don't know if switching
that would cause the case of a non-existing {{dbname}} case to regress, though.
