----------------------------------------
Hi,
I have a question - does EXPLAIN execute any user-specified code? I'm faced
with a environment issue where I don't want to execute any user-specified code
(UDFs,etc) or run anything, merely to syntax check. Would EXPLAIN still fit my
need?
Thanks!

> Hive currently doesn't support a dry run option. For some complex queries we
> just want to verify the query syntax initally before running it. A dry run
> option where just the parsing is done without actual execution is a good
> option.
