      Description

      select ...
      (
      SubQuery involving MapReduce
      union all
      SubQuery involving MapReduce
      );

      or

      select ...
      (SubQuery involving MapReduce)
      join
      (SubQuery involving MapReduce)
      ;

      If both the subQueries finish at nearly the same time, there is a race
      condition in which the results of the subQuery finishing last will be completely missed.
