> Today DataSource Task pull InputSplits from JobManager to achieve better
> performance, however, when a DataSourceTask failed and rerun, it will not get
> the same splits as its previous version. this will introduce inconsistent
> result or even data corruption.
> Furthermore, if there are two executions run at the same time (in batch
> scenario), this two executions should process same splits.
> we need to fix the issue to make the inputs of a DataSourceTask
> deterministic. The propose is save all splits into ExecutionVertex and
> DataSourceTask will pull split from there.
