Chesnay Schepler commented on FLINK-27487: ------------------------------------------ [~tashoyan] yes; I created a separate ticket: FLINK-28488 > KafkaMetricWrappers do incorrect cast > ------------------------------------- > > Key: FLINK-27487 > URL: https://issues.apache.org/jira/browse/FLINK-27487 > Project: Flink > Issue Type: Bug > Components: Connectors / Kafka, Runtime / Metrics > Affects Versions: 1.15.0 > Reporter: Chesnay Schepler > Assignee: Fabian Paul > Priority: Blocker > Labels: pull-request-available > Fix For: 1.15.1, 1.16.0 > > > 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
