Subject [jira] [Commented] (HIVE-14731) Use Tez cartesian product edge in Hive (unpartitioned case only)
Date Mon, 12 Dec 2016 18:08:58 GMT


Gunther Hagleitner commented on HIVE-14731:

Two quick comments: a) listing the entire output of the x prod in the golden file makes the
patch unnecessarily large. Can you either do a sum(hash(...)) over the output or use smaller
tables? b) this patch probably warrants more tests, unless there are other places in the q
files that already cover that.

> Given cartesian product edge is available in Tez now (see TEZ-3230), let's integrate
it into Hive on Tez. This allows us to have more than one reducer in cross product queries.
