(Updated 2011-12-07 08:15:06.858543) Review request for hive, John Sichi and Carl Steinbach. Changes ------- rebased to trunk Summary ------- If map aggregation is set to false, DISTRIBUTED BY followed by GROUP BY with same key fails in runtime. ReduceSinkDeDuplication optimization should be avoid if child of child RS is GBY. This addresses bug HIVE-2329. https://issues.apache.org/jira/browse/HIVE-2329 Diffs (updated) ----- ql/src/java/org/apache/hadoop/hive/ql/optimizer/ReduceSinkDeDuplication.java e91b4d5 ql/src/test/queries/clientpositive/reduce_deduplicate_exclude_gby.q PRE-CREATION ql/src/test/results/clientpositive/reduce_deduplicate_exclude_gby.q.out PRE-CREATION Diff: https://reviews.apache.org/r/1313/diff Testing (updated) ------- test added : reduce_deduplicate_exclude_gby.q Thanks, Navis
