Subject Re: Kafka producer perf script throw java.io.IOException
Date Tue, 10 Feb 2015 02:38:11 GMT
The new producer uses a different built-in metrics package. Currently, it
only supports a jmx reporter for the metrics. So you will have to get the
metrics from jmx.

We can add the csv reporter in ProducerPerformance for the new producer by
using the new metrics api. Could you file a jira for that?

Thanks,

Jun
