Subject Cross join/cartesian product explanation
Date Fri, 06 Nov 2015 21:15:27 GMT
Hi all,

Over the last few week I’ve been trying to use cross joins/cartesian products and was wondering
why, exactly, this all gets sent to one reducer. All I’ve heard or read is that Hive can’t/doesn’t
parallelize the job. Is there some code people can point me to? Does anyone have a workaround?
