----------------------------------
Summary: No pushdown subquery's group by key in outside filter
Key: HIVE-3568
URL: https://issues.apache.org/jira/browse/HIVE-3568
Project: Hive
Issue Type: Bug
Components: Query Processor
Reporter: Gang Tim Liu
Priority: Minor
pushdown doesn't happen with group by in subquery and group by key in outside
filter.
select * from (select x, count(1) from fact_daily where ds ='1' group by x)
subq where x = 484;
subquery still scans the partition.
expect only scan x = 484.
