-----------------------------------
Summary: MapReduce queries in Pigmix outputs different results
than Pig's
Key: PIG-3915
URL: https://issues.apache.org/jira/browse/PIG-3915
Project: Pig
Issue Type: Bug
Components: tools
Affects Versions: 0.12.0
Reporter: Keren Ouaknine
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
