             Summary: Client Selector can drop idle connections without notifying NetworkClient
                 Key: KAFKA-2266
                 URL: https://issues.apache.org/jira/browse/KAFKA-2266
             Project: Kafka
          Issue Type: Bug
            Reporter: Jason Gustafson
            Assignee: Jason Gustafson


I've run into this while testing the new consumer. The class org.apache.kafka.common.networ.Selector has code to drop idle connections, but when one is dropped, it is not added to the list of disconnections. This causes inconsistency between Selector and NetworkClient, which depends on this list to update its internal connection states. When a new request is sent to NetworkClient, it still sees the connection as good and forwards it to Selector, which results in an IllegalStateException.
