hnakamor opened a new issue #7108: Data ingestion fails on Quantiles DoublesSketch containing NULL When usingDefaultValueForNull = false
URL: https://github.com/apache/incubator-druid/issues/7108
Hi All,
In 0.13.0-incubating, setting usingDefaultValueForNull = false and using a quantilesDoubleSketch aggregator at ingestion containing NULL will result in the following exception during index task:
```
