Victoria Markman commented on DRILL-3003:
-----------------------------------------
As Jason pointed out, this is perfectly valid query as well as this one:
{code}
0: jdbc:drill:schema=dfs> select * from t1 right outer join t2 on (t1.a1 =
t2.a2 and t1.a1 = ( select max(a3) from t3 ));
Error: PARSE ERROR: java.lang.NullPointerException
[Error Id: afe70dd7-199f-4dae-802e-2b5e08f13af8 on atsqa4-133.qa.lab:31010]
(state=,code=0)
{code}
> NPE on incorrect query (and instead of where clause)
