-------------------------------------
Summary: 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
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?
