Review Comment:
Sonar marked it as [code
smell](https://sonarcloud.io/project/issues?issues=AYJpdDZw9k-CsauE5Bp5&open=AYJpdDZw9k-CsauE5Bp5&id=apache_hive)
because for non-`Serializable` classes the modifier is a no-op and it's
suggested to remove it.

> Key: HIVE-26243
> URL: https://issues.apache.org/jira/browse/HIVE-26243
> Project: Hive
> Issue Type: Improvement
> Components: UDF, Vectorization
> Affects Versions: 4.0.0-alpha-2

> _ds_kll_sketch_ UDAF does not have a vectorized implementation at the moment,
> the present ticket aims at bridging this gap.
> This is particularly important because vectorization has an "all or nothing"
> approach, so if this function is used at the side of vectorized functions,
> they won't be able to benefit from vectorized execution.
