----------------------------------------

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.
