Review Comment:
   If task2 submit fail, `In PipelineFragmentContext::submit` will cancel the context and set `_total_tasks` to 1.
   If `_closed_tasks == _total_tasks` represents task1 is close, we try to exec `_close_action`.
   if `_closed_tasks != _total_tasks`, task1 will exec `_close_action`.
