Krzysztof Zarzycki created KYLIN-4077:
-----------------------------------------
Summary: Kylin does not handle queries with GROUP BY constant.
Key: KYLIN-4077
URL: https://issues.apache.org/jira/browse/KYLIN-4077
Project: Kylin
Issue Type: Bug
Reporter: Krzysztof Zarzycki
I connect Tableau to Kylin and one of the queries it generates has a clause
{{GROUP BY 1.100000001}} , that Kylin cannot handle.
{code:java}
>From line 1, column 8 to line 1, column 15: Aggregate expression is illegal in
>GROUP BY clause while executing SQL: "select count(*) from
>report_sales.kylin_sales_model GROUP BY 1.1000001 LIMIT 50000" {code}
Alternatively, I translated the query with Hive JdbcStorageHandler to {{GROUP
BY TRUE}} and that is also not handled.
{code:java}
No DataTypeSerializer for type _literal_type while executing SQL: "select
count(*) from report_sales.kylin_sales_model GROUP BY TRUE LIMIT 50000" {code}
Expected behavior:
Kylin supports queries with {{GROUP BY <any constant>}}
