Review request for hive and Ashutosh Chauhan. Repository: hive-git Description ------- in ql/src/java/org/apache/hadoop/hive/ql/ppd/OpProcFactory.java, line 477, when aliases contains empty string "" and key is an empty string "" too, it assumes that aliases contains key. This will trigger incorrect PPD. To reproduce it, apply the HIVE-10455 and run cbo_subq_notin.q. Diffs ----- ql/src/java/org/apache/hadoop/hive/ql/optimizer/calcite/translator/HiveOpConverter.java 4f19caf Diff: https://reviews.apache.org/r/34897/diff/ Testing ------- Thanks, pengcheng xiong
