Description
Consider supporting existing UDF libraries, e.g.:
https://github.com/Esri/spatial-framework-for-hadoop/blob/master/hive/src/main/java/com/esri/hadoop/hive/ST_Aggr_Union.java
Will probably need to implement a layer on top of https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/UDF.java
Imported from Jira [BEAM-3609](https://issues.apache.org/jira/browse/BEAM-3609). Original Jira may contain additional context.

Contributor guide
Research direction
Start by reading the Hive UDF base class in ql/src/java/org/apache/hadoop/hive/ql/exec/UDF.java and the referenced Esri ST_Aggr_Union implementation. The issue does not identify Beam files, tests, or a defined compatibility scope, so the work is done only after the supported Hive UDF behavior and validation approach are agreed.
