Bill Bejeck created KAFKA-19504: ----------------------------------- Summary: AdminClient creates and adds second metrics reporter Key: KAFKA-19504 URL: https://issues.apache.org/jira/browse/KAFKA-19504 Project: Kafka Issue Type: Task Components: clients Affects Versions: 4.1.0 Reporter: Bill Bejeck
The `AdminClient` adds a telemetry reporter to the metrics reporters list in the constructor. The problem is that the reporter was already added in the `createInternal` method. In the `createInternal` method call, the `clientTelemetryReporter` is added to a `List<MetricReporters>` which is passed to the `Metrics` object, will get closed when `Metrics.close()` is called. But adding a reporter to the reporters list in the constructor is not used by the `Metrics` object and hence doesn't get closed, causing a memory leak. Note, this problem only exists if telemetry metrics is enabled for the `AdminClient` and it is disabled by default. -- This message was sent by Atlassian Jira (v8.20.10#820010)
