The trace above indicates the Broker is trying to deserialize a sketch sent to it by a data server (like a Historical) as the result of a partial aggregation. So, it's not directly from something stored in a segment. It's been run through an aggregator. @AlexanderSaydakov, @leerho, is it possible that there is some issue when a sketch written with DataSketches 1.1.0 (as the upgraded Historical would do) is read by DataSketches 0.13.3 (as the Broker would do)? @capistrant, did you get the same stack trace as @DockerLive? If not could you post yours too? Btw, you should be able to get @leerho the image he asked for by sending the Historical the same query that the Broker did. You'll get a base64 encoded version of the sketch. The best way to get the same query the Broker issued is probably to either: - use wireshark to capture it and then reissue it - enable request logging on one of your Historicals and then copy the query out of the request log ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
