Roll back my last comment. The hive-metastore*.jar doesn't contain ErrorMsg.java.

bq.  Summary
bq.  -------
bq.  
bq.  Now when creating table in specific database, if that database doesn't exist Hive will
return an error informing about that, instead of throwing Null Pointer Exception. Null Pointer
happens during semantic analysis, so it seems reasonable to return an error before the code
that would throw null pointer (Warehouse.getDatabasePath()) executes.
