These are the test where I observed failures when I changed this case to LONG only groupby_grouping_sets_grouping.q,groupby_grouping_window.q,groupby_rollup_empty.q,udf_width_bucket.q,vector_grouping_sets.q Some pointers https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/calcite/translator/HiveGBOpConvUtil.java#L1188 https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/calcite/translator/HiveGBOpConvUtil.java#L866 https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/parse/SemanticAnalyzer.java#L3131 The rabbit hole went a little deep, so I handled it in the UDF. - Prasanth_J ----------------------------------------------------------- This is an automatically generated e-mail.
