https://github.com/apache/kafka/pull/16548
> Admin Client connections.max.idle.ms should be 9 minutes by default
> -------------------------------------------------------------------

> Key: KAFKA-16057
> URL: https://issues.apache.org/jira/browse/KAFKA-16057
> Project: Kafka
> Issue Type: Bug
> Reporter: Marcin Kuthan
> Assignee: Ksolves
> Priority: Minor
>
> Producer and consumer define connections.max.idle.ms to 9 minutes but Admin
> uses 5 minutes by default.
> When the connection.max.idle.ms is equal to metadata.max.age.ms (5 minutes)
> admin client disconnects frequently. I observe the following log in Kafka
> Connect cluster:
> {code:java}
> [AdminClient clientId=MyClientName--shared-admin] Node XYVZ disconnected.
> {code}
> AdminClient is trying to fetch metadata on every 5 minutes but the connection
> has been already closed due to the connection.max.idle.ms.
> As a workaround I defined connection.max.idle.ms property explicitly to 9
> minutes in Kafka Connect configuration. This way admin, producers and
> consumers use the same configuration.
> I'm wondering why Admin uses different default for connection.max.idle.ms
> than Consumer / Producer. Bug or feature?
