[jira] [Created] (APEXMALHAR-2450) UniqueCounter emits empty maps even when there is no input

Thomas Weise created APEXMALHAR-2450:
----------------------------------------

             Summary: UniqueCounter emits empty maps even when there is no input
                 Key: APEXMALHAR-2450
                 URL: https://issues.apache.org/jira/browse/APEXMALHAR-2450
             Project: Apache Apex Malhar
          Issue Type: Bug
            Reporter: Thomas Weise
            Priority: Minor


No inputs received, empty maps produced. The operator is probably only used in demos, and that's how the issue was noticed. Word count result files filled with just {}s. The suggested solution is to change the operator to only emit non-empty results.
