You said you used spark-alchemy for HLL calculation. This most likely won't work as it's binary format is not compatible with druid HLL. You need to use druid-hll to ensure binary sketch compatibility. Once you use druid-hll API to calculate and/or aggregate your HLLs, you then need to base64 encode it before passing data to druid ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
