> Hello,
> The Pigmix benchmark has 17 queries comparing Pig to MapReduce Java. Some of
> these queries are not outputting the same results in Pig and MapReduce.
> Looking into the outputs, it seems the errors reside in the MapReduce code.
> For example, L6 has no output because the output of the map function sends
> the wrong key to the reducer: "query_term" (field 3) instead of "timespent"
> (field 2). Hence an exception is thrown, and there is no output to the query
> in MapReduce. I am planning to submit a patch once I fixed all the queries in
> MapReduce :)
> Thanks,
> Keren
