Kafka 0.8.2.2 throwing exception using release 0.4.1

[agolomoodysaada]

I added kafka.metrics.reporters=com.airbnb.kafka.kafka08.StatsdMetricsReporter to my consumer.properties file and i see this

$ bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test -from-beginning --consumer.config config/consumer.properties

Try using metric.reporters rather than kafka.metrics.reporters

$ jar -tf kafka-statsd-metrics2-0.4.1.jar

suggests

kafka.metrics.reporters=com.airbnb.kafka.KafkaStatsdMetricsReporter

I'm using the same versions as you and this got me past the ClassNotFoundException, but I'm not seeing anything sent to statsd yet.

Got it partially working. Dropping java-dogstatsd-client-2.0.11.jar into libs/ and downgrading kafka to 0.8.2.1 (an exact match for 0.4.1/build.gradle#L26) seems to have most of the metrics showing up, minus the tag-requiring metrics mentioned in https://github.com/airbnb/kafka-statsd-metrics2/issues/9.
