Correlated subquery: works, returns correct result
{code}
0: jdbc:drill:schema=dfs> select * from t2 where a2 not in ( select a1 from t1
where t2.b2 = t1.b1 );
+------------+------------+------------+
| a2 | b2 | c2 |

count (\*) works
{code}
0: jdbc:drill:schema=dfs> select t2.c2, count(*) from t2 where a2 not in (
select a1 from t1 where t2.b2 = t1.b1 ) group by t2.c2 order by t2.c2;

{code}
count(<column name>) does not work and throws an error.
Postgres returns result in this case. I'm not sure what is wrong with this
query and error does not tell me anything ....
{code}
0: jdbc:drill:schema=dfs> select t2.c2, count(t2.b2) from t2 where a2 not in (
select a1 from t1 where t2.b2 = t1.b1 ) group by t2.c2 order by t2.c2;
Query failed: IllegalArgumentException: Target must be less than target count, 2
