[jira] [Created] (DRILL-4321) Difference in results count distinct with min max query on JDK8

Khurram Faraaz created DRILL-4321:
-------------------------------------

             Summary: Difference in results count distinct with min max query on JDK8
                 Key: DRILL-4321
                 URL: https://issues.apache.org/jira/browse/DRILL-4321
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 1.4.0
         Environment: 4 node cluster
            Reporter: Khurram Faraaz


count distinct query with min max and group by and order by returns incorrect results on MapR Drill 1.4.0, MapR FS 5.0.0 GA and JDK8

The difference is in the way we round off values after the decimal when using JDK8.

Expected results file can be found here
https://github.com/mapr/drill-test-framework/blob/master/framework/resources/Functional/aggregates/aggregation/count_distinct/with_min_max_c_float_group_by_1_cols.res

Failing query is Functional/aggregates/aggregation/count_distinct/
with_min_max_c_float_group_by_1_cols.sql

{noformat}
select count(distinct c_float), max(c_float), min(c_float) from alltypes_with_nulls group by  c_date order by  c_date;
{noformat}
