> 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.
