Subject drop table: no err on nonexistant table?
Date Mon, 06 Aug 2012 18:06:03 GMT
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?

Thank you.
