Namit Jain commented on HIVE-840:
---------------------------------
There are existing error messages which are used with parameters: look at
TABLE_ALREADY_EXISTS.
Cant you follow the same approach ? The only restriction is that the column
name will appear at the end,
which might be acceptable.
> no error if user specifies multiple columns of same name as output
