Review Comment:
@adoroszlai
Originally, we shut down the executor after each run because we were
creating a brand-new executor just for that single run. Once the tasks were
finished, we shut it down to clean up the resources.
But I guess I will remove this shutdown from the reprocess otherwise there
is no point of keeping the executor in the constructor for shairing.
