> There is a topology of 3 operator, such as, source, parser, and persist. Occasionally, 5 subtasks of the source encounters exception and turns to failed, at the same time, one subtask of the parser runs into exception and turns to failed too. The jobmaster gets a message of the parser's failed. The jobmaster then try to cancel all the subtask, most of the subtasks of the three operator turns to canceled except the 5 subtasks of the source, because the state of the 5 ones is already FAILED before jobmaster try to cancel it. Then the jobmaster can not reach a final state but keeps in  Failing state meanwhile the subtask of the source kees in canceling state.
