Subject [GitHub] flink pull request: [FLINK-1521] Chained operators respect reuse

    The problem here I think that an error caused by the reusing mapper could be very hard
to detect. So some users might have it but they don't realise.
    
    For streaming we copy the input at every chained function call just to be on the safe
side, but we'll have to reintroduce the object reuse mode.
