Re: Weird results with Spark SQL Outer joins

Gourav, I wish that was case, but I have done a select count on each of the two tables individually and they return back different number of rows: dps.registerTempTable("dps_pin_promo_lt") swig.registerTempTable("swig_pin_promo_lt") dps.count() RESULT: 42632 swig.count() RESULT: 42034

Re: Weird results with Spark SQL Outer joins

This shows that both the tables have matching records and no mismatches. Therefore obviously you have the same results irrespective of whether you use right or left join. I think that there is no problem here, unless I am missing something. Regards, Gourav On Mon, May 2, 2016 at 7:48 PM, kpeng1

Re: Weird results with Spark SQL Outer joins

Hi Kevin, Thanks. Please post the result of the same query with INNER JOIN and then it will give us a bit of insight. Regards, Gourav On Mon, May 2, 2016 at 7:10 PM, Kevin Peng wrote: > Gourav, > > Apologies. I edited my post with this information: > Spark version: 1.6 >
