Re: INSERT non-static data to array?
My understanding is that LATERAL VIEW goes the other direction: takes an array and makes it into separate rows.  I use that a lot.  But I also need to go the other way sometimes: take a bunch of rows and squeeze them down into an array.  Please correct me if I'm missing something.

i think you could select into as sub query and then use lateral view.not exactly the same but something similar could be done,.

I'm assuming that a) SQL1999 array INSERT via subquery is not (yet) implemented in Hive, and b) there is also no other way to load dynamically generated data into an array<> column?  If my assumption in a) is true, does a Jira item need to be created for it?
