Erik van Oosten commented on KAFKA-960: --------------------------------------- Metrics 4.x was released not so long ago. The core is binary compatible with metrics 3.x. However, many modules were split from the core and these got a different package name (and are therefore not compatible). For just collecting, you're probably fine. Please also know that Metrics 5.x is on standby for more then half a year. Metrics 5 will support tags. Metrics 5 is not binary compatible. I recommend upgrading to Metrics 4. > Upgrade Metrics to 3.x > ---------------------- > > Key: KAFKA-960 > URL: https://issues.apache.org/jira/browse/KAFKA-960 > Project: Kafka > Issue Type: Improvement > Components: metrics > Affects Versions: 0.8.1 > Reporter: Cosmin Lehene > Priority: Major > > Now that metrics 3.0 has been released > (http://metrics.codahale.com/about/release-notes/) we can upgrade back -- This message was sent by Atlassian JIRA (v7.6.3#76005)
