Hi, My samza job has following metrics configuration:
serializers.registry.metrics.class=org.apache.samza.serializers.MetricsSnapshotSerdeFactory systems.kafka.samza.factory=org.apache.samza.system.kafka.KafkaSystemFactory systems.kafka.consumer.zookeeper.connect=zk11:3181,zk12:3181,zk13:3181 systems.kafka.producer.bootstrap.servers=buka1:9096,buka2:9096,buka3:9096 systems.kafka.streams.samza-metrics.samza.msg.serde=metrics metrics.reporter.snapshot.class=org.apache.samza.metrics.reporter.MetricsSnapshotReporterFactory metrics.reporter.snapshot.stream=kafka.samza-metrics metrics.reporters=snapshot And the job is deployed on yarn, after job started, everything is fine, I also can find coordinator stream and checkpoint stream in the same kafka cluster, but there is no samza-metrics stream.
