[jira] [Updated] (FLINK-27487) KafkaMetricWrappers do incorrect cast
[ https://issues.apache.org/jira/browse/FLINK-27487?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chesnay Schepler updated FLINK-27487:
-------------------------------------
Description:
In FLINK-24765 the kafka metric wrappers that bridge kafka metrics into our metric system were migrated from the deprecated {{KafkaMetric#value}} to {{#metricValue}}.
This migration was done incorrectly. It was assumed that #metricValue behaves similar to #value in that it always returns a double, but this is not the case, as they may also return longs or strings.
This results in these metrics throwing exceptions, which generally breaks the reporter mechanism completely.
