             Summary: Error message must provide information about grouping column
                 Key: DRILL-3252
                 URL: https://issues.apache.org/jira/browse/DRILL-3252
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 1.0.0
            Reporter: Khurram Faraaz
            Assignee: Jinfeng Ni
            Priority: Minor


Enable window functions and run the below query. The error message is not very clear. The grouping column is columns[4] cast as TIMESTAMP, and the order by column in also columns[4] but here it is cast as INT.

The error message just says 'columns' is not being grouped. We need to report which column it is. 

{code}
0: jdbc:drill:schema=dfs.tmp> SELECT MAX(cast( columns[4] as TIMESTAMP )) OVER(PARTITION BY cast( columns[4] as TIMESTAMP) ORDER BY cast( columns[4] as INT )) FROM `allData.csv` group by cast(columns[4] as TIMESTAMP);
Error: PARSE ERROR: From line 1, column 109 to line 1, column 115: Expression 'columns' is not being grouped
