In datasketches-hive, null is treated as empty set. https://github.com/apache/datasketches-hive/blob/master/src/main/java/org/apache/datasketches/hive/theta/UnionSketchUDF.java In this case, `theta_sketch_union(null, null)` returns empty sketch, not `null`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
