-Re: Pig vs hive performance
Dan Richelson 2012-10-04, 02:50
Anecdotally I can say that Pig seems to scale down better than Hive.
We see this in tests- hive scripts running small amounts of data take
much longer than similar Pig scripts. Hive parallel settings are
enabled. I think this has to do with the fact that there doesn't seem
to be a 'local' mode for hive- you have to run it as mapreduce jobs
(either embedded or on a cluster). Please correct me if I am wrong
