I'm wrapping hive in a web tool and would like to do some basic error-checking. If an attempt is made to drop a table that doesn't exist, I would like to show an error message. The problem is, hive doesn't seem to produce any sort of error when dropping a table that doesn't exists. Furthermore, if hive is run on the command line (-e) it doesn't return an error status. Therefore, I think the only way to detect such an error is to actually inspect the table list (show tables) and manually see if the drop attempt will find a corresponding table.
Can I get an error of some sort on this or is it not possible?
