             Summary: hello-samza wikipedia-parser is using json serde for metrics
                 Key: SAMZA-730
                 URL: https://issues.apache.org/jira/browse/SAMZA-730
             Project: Samza
          Issue Type: Bug
          Components: hello-samza
            Reporter: Steven Aerts


The configuration for the wikipedia-parser writes metrics to a kafka topic but uses the default {{json}}-serde instead of the {{metrics}}-serde for it.
The metrics serde is defined, but not used in its {{wikipedia-parser.properties}} file.

I propose to fix it by configuring it

{code} 
systems.kafka.streams.metrics.samza.msg.serde=metrics
{code}
