--------------------------------------
Summary: UNION does not work with Double
Key: BEAM-7361
URL: https://issues.apache.org/jira/browse/BEAM-7361
Project: Beam
Issue Type: Bug
Components: dsl-sql
Affects Versions: 2.12.0, 2.11.0
Reporter: Chikara Mizokami
The SQL operation UNION does not work on numerical columns such as DOUBLE.
The error shown is related to GroupByKey, but I am not sure why UNION includes
any steps that require GroupBy which blocks non-deterministic columns.
Also, would this issue be solved if we implement UNION with a different
approach such as BEAM-3721, BEAM-3722 ?
