scrawfor opened a new issue #9736:
URL: https://github.com/apache/druid/issues/9736
Please provide a detailed title (e.g. "Broker crashes when using TopN query
with Bound filter" instead of just "Broker crashes").
### Affected Version
v0.18 (upgraded from 0.16.0)
### Description
The HLLSketchMerge aggregator is failing for some of our metrics after
upgrading to druid 0.18.0. Reverting back to 0.16.0 fixes the issue. I have
isolated specific segments where the issue occurs, loaded those moved those
segments back to our 0.16 historical and have been successfully able to query
the same metric.
Re-indexing data does not seem to fix the issue.
