0: jdbc:drill:schema=dfs> select distinct count(distinct a1) from t1 group by b1 order by 1;
Query failed: SqlValidatorException: Expression 'COUNT(`t1`.`a1`)' is not in the select clause
Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}

Replaced ordinal with function: fails
{code}
0: jdbc:drill:schema=dfs> select distinct count(distinct a1) from t1 group by b1 order by count(distinct a1);
Query failed: SqlValidatorException: Expression 'COUNT(DISTINCT `a1`)' is not in the select clause
Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}

Different aggregate function without DISTINCT clause: fails
{code}
0: jdbc:drill:schema=dfs> select  distinct sum(a1) from t1 group by b1 order by 1;
Query failed: SqlValidatorException: Expression 'SUM(`t1`.`a1`)' is not in the select clause
Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}

Added alias to the function and order by alias: fails
{code}
0: jdbc:drill:schema=dfs> select  distinct sum(a1) as x from t1 group by b1 order by x;
Query failed: SqlValidatorException: Expression 'SUM(`t1`.`a1`)' is not in the select clause
Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}
