Summary: Remove the subclass of KafkaMetricsGroup
Key: KAFKA-17222
URL: https://issues.apache.org/jira/browse/KAFKA-17222
Project: Kafka
Issue Type: Improvement
Reporter: Chia-Ping Tsai
Assignee: bboyleonp
There are subclass of KafkaMetricsGroup which have override `metricName`
[0][1][2]. They are used to keep metrics compatibility. Now, KafkaMetricsGroup
has the new constructor which can define the package and class name, and so we
don't need to override the `metricName` anymore.
