Hi all, Sorry if I am missing something obvious but is there an inverse of an explode?
E.g. given t1 ID Name 1 Tim 2 Tim 3 Tom 4 Frank 5 Tim Can you create t2: Name ID Tim 1,2,5 Tom 3 Frank 4 In Oracle it would be a select name,collect(id) from t1 group by name I suspect in Hive it is related to an Array but can't find the syntax Thanks for any pointers, Tim
