Jiehong Lian commented on HIVE-12778: ------------------------------------- It's a bug when the having clause contains the aggregator with distinct hint, while the aggregator does not in the select clause. such as: {code:java} // code placeholder SELECT key FROM src GROUP BY key HAVING COUNT(value) >= 4 and count(distinct value) > 1 ;{code} I have a patch fix the bug. > Having with count distinct doesn't work for special combination > --------------------------------------------------------------- > > Key: HIVE-12778 > URL: https://issues.apache.org/jira/browse/HIVE-12778 > Project: Hive > Issue Type: Bug > Components: Hive > Affects Versions: 1.1.0, 1.2.1 > Reporter: Peter Brejcak > Priority: Major > > There is problem for combination of count(distinct ) in having clause without > count(distinct ) in select clause. > First case returns error *FAILED: SemanticException [Error 10002]: Line > Invalid column reference* (unexpected) > If I add count(distinct ) to select clause result is ok (expected). > Please run code to see it. > Steps to reproduce: > {code} > create table table_subquery_having_problem (id int, value int); > insert into table table_subquery_having_problem values (1,1); > insert into table table_subquery_having_problem values (1,2); > insert into table table_subquery_having_problem values (1,3); > insert into table table_subquery_having_problem values (1,4); > insert into table table_subquery_having_problem values (1,5); > insert into table table_subquery_having_problem values (1,6); > insert into table table_subquery_having_problem values (1,7); > insert into table table_subquery_having_problem values (1,8); > insert into table table_subquery_having_problem values (1,9); > select x.id from table_subquery_having_problem x > group by x.id > having count(distinct x.value)>1; -- result is ERROR > select x.id, count(distinct x.value) from table_subquery_having_problem x > group by x.id > having count(distinct x.value)>1; --result is OK > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
