(Updated 2011-10-12 11:41:33.601642) Review request for hive, Yongqiang He and Liyin. Summary ------- in mapjoin_subquery.q there is a query? SELECT /*+ MAPJOIN(z) */ subq.key1, z.value FROM (SELECT /*+ MAPJOIN */ x.key as key1, x.value as value1, y.key as key2, y.value as value2 FROM src1 x JOIN src y ON (x.key = y.key)) subq JOIN srcpart z ON (subq.key1 = z.key and z.ds='2008-04-08' and z.hr=11); when dump x and z to a local file,there all dump to the same file, so we lost the data of x Diffs ----- http://svn.apache.org/repos/asf/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/HashTableSinkOperator.java 1182256 http://svn.apache.org/repos/asf/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/MapJoinOperator.java 1182256 http://svn.apache.org/repos/asf/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/MapredLocalTask.java 1182256 http://svn.apache.org/repos/asf/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/Utilities.java 1182256 http://svn.apache.org/repos/asf/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/optimizer/MapJoinProcessor.java 1182256 http://svn.apache.org/repos/asf/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/optimizer/physical/LocalMapJoinProcFactory.java 1182256 http://svn.apache.org/repos/asf/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/parse/QBJoinTree.java 1182256 http://svn.apache.org/repos/asf/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/plan/HashTableSinkDesc.java 1182256 http://svn.apache.org/repos/asf/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/plan/MapJoinDesc.java 1182256 Diff: https://reviews.apache.org/r/2356/diff Testing ------- Thanks, bin
