That is cool! I didn’t know this feature existed at all.

I’ve been using https://cwiki.apache.org/confluence/display/Hive/LanguageManual 
as the online manual for Hive, and I don’t see ‘reflect’ mentioned there. I see 
it here, though: http://archive.cloudera.com/cdh/3/hive/udf/reflect.html. This 
archive site also contains some good info on variable substitution in Hive 
scripts, which I didn’t know was available either.

Thanks for the tip on ‘reflect’ !
