      An Impala query fails with error "ERROR: IllegalStateException: null"

      Problem:
      ========
      Customer has provided the following reproduction case:

      create table tab1( tdate decimal(10,0) )
         partitioned by (p_tdate int);
       
      select
         *
      from
         (SELECT
             t.*
      FROM
      tab1 t
      INNER JOIN
      (SELECT 20191004 tdate ) d
      WHERE
      t.p_tdate < d.tdate
      ) q
      where
         p_tdate <> tdate
         and P_TDATE = 20191004;
