clintropolis opened a new pull request #7730: add support for multi-value string dimensions for 'HllSketch' build aggregator
URL: https://github.com/apache/incubator-druid/pull/7730
Without this patch, attempting to use `HLLSketchBuild` aggregator on a multi-value string dimension results in a query failure caused by:
```
java.lang.RuntimeException: org.apache.druid.java.util.common.IAE: Unsupported type class java.util.Arrays$ArrayList
```
