[jira] [Created] (BEAM-8529) Samza runner does not allow using Void as key in grouping operations

Jan Lukavský created BEAM-8529:
----------------------------------

             Summary: Samza runner does not allow using Void as key in grouping operations
                 Key: BEAM-8529
                 URL: https://issues.apache.org/jira/browse/BEAM-8529
             Project: Beam
          Issue Type: Bug
          Components: runner-samza
    Affects Versions: 2.17.0
            Reporter: Jan Lukavský


Using {{Void}} as key type for grouping operations fails due to the fact that its only value is {{null}} and SamzaRunner does not accept using {{null}} values as keys. Other runners seem to work fine with that.
