Re: Extending Explode
So the explode output should be in the order of the array or the map you
are exploding.

I think you could use rank or row-sequence to give the exploded attay a
number. If that does not wok adding a new udf might make more sence then
extwnding in this case.:

if I should extend the current explode function or if I should write a
completely new function. Any thoughts on what will be more useful and more
likely to be added to the hive-trunk would be greatly appreciated.
