Hi @jihoonson > This log means, you got two segments of overlapping intervals and same version. This is never allowed since Druid doesn't know what segment to read in this case. Druid should never create such segments of overlapping intervals but same version. Can you check why and how they were created? The two partially overlapping segments with same version are created by the compaction task as described in step 3 of bug duplication steps above. According to the log of compaction task, I found that the two input partially overlapping segments(with different version) are arranged to compact in two different `indexSpec`, and creating a `DAY` granularity segment and an `HOUR` granularity segment correspondingly but with same version. And I pasted the log of compaction task [here](https://gist.github.com/yuanlihan/a3f54ca6eb6ba7508fcfa653065c79eb) FYI. And you can also easily reproduce this bug locally according to the steps listed above. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
