      Description

      STEPS TO REPRODUCE:

      1. Create a table:

      CREATE TABLE t (a1 INT, a2 INT);
      INSERT INTO TABLE t VALUES (1,1),(1,2),(2,1),(2,2);

      2. SET hive.support.quoted.identifiers to "none":

      SET hive.support.quoted.identifiers=none;

      3. Run the query:

      SELECT `(a1)?+.+` FROM t
      UNION
      SELECT `(a2)?+.+` FROM t;

      ACTUAL RESULT:
      The query fails with an exception:
