zhaohm3 updated HIVE-9336:
--------------------------
Description:
Currently, when Hive parses GROUPING SETS clauses, and if there are some
expressions that were composed of two or more common subexpressions, then the
first element of those expressions can only be a simple Identifier without any
qualifications, otherwise Hive will throw ParseException during its parser
stage. Therefore, Hive will throw ParseException while parsing the following
HQLs:
drop table test;
create table test(tc1 int, tc2 int, tc3 int);
explain select test.tc1, test.tc2 from test group by test.tc1, test.tc2
grouping sets(test.tc1, (test.tc1, test.tc2));
explain select tc1+tc2, tc2 from test group by tc1+tc2, tc2 grouping
sets(tc2, (tc1 + tc2, tc2));
drop table test;
