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.
