> The plan ql/src/test/results/clientpositive/input3_limit.q.out shows that there are 2 map-reduce jobs:
> The first one is distributed and sorted as is specified by the query. The reducer side has LIMIT 20.
> The second one (single reducer job imposed by LIMIT 20) does not have the same sort order, so the final result is non-deterministic.
