> We define a new abstract special exception called PartitionException to indicate the downstream task failure in consuming upstream partition. This special exception is reported to JobMaster as a hint for unavailable partition data, and then JobMaster could track the upstream executions to restart for reproducing the partition data.
> We make current PartitionNotFoundException extend PartitionException, because it is reasonable to restart producer task when the requested partition is already released.
