-------------------------------------
Summary: Missing partition by key in OVER clause causes
RelOptPlanner$CannotPlanException
Key: DRILL-3175
URL: https://issues.apache.org/jira/browse/DRILL-3175
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 1.0.0
Reporter: Khurram Faraaz
Assignee: Jinfeng Ni
Since the two inputs to OVER clause are optional. Test that uses only order by
clause with order by column results in CannotPlanException
{code}
0: jdbc:drill:schema=dfs.tmp> select count(columns[3]) over ( order by
columns[13]) from `airports.csv`;
