> In this patch, we modify the codes corresponding to runApproximateJob so that we can
get a result when the specified percent of tasks succeed.
> In a production environment, 'long tail' is a common urgent problem. In practice, as
long as we can get a specified percent of  tasks' results, we can guarantee the final results.
And this is a common requirement in the practice of machine learning algorithms.
