> You might check if the sketch that being wrapped (with a seedHash ==0) is an empty sketch. Empty sketches no longer have a seedHash, because there is no data to hash. We'd need to work around it on the newer server side, because we can't change the code running on the old servers (they're the old ones)! So perhaps we insert some code into Druid that detects empty sketches on _write_, and then replaces them with a constant defined older sketch image that both versions could interpret (with the seedHash set to -27700). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
