Sanjana Kaundinya resolved KAFKA-9893.
--------------------------------------
Resolution: Implemented
> Configurable TCP connection timeout and improve the initial metadata fetch
> --------------------------------------------------------------------------
>
> Key: KAFKA-9893
> URL: https://issues.apache.org/jira/browse/KAFKA-9893
> Project: Kafka
> Issue Type: New Feature
> Reporter: Cheng Tan
> Assignee: Cheng Tan
> Priority: Major
>
> This issue has two parts:
> # Support transportation layer connection timeout described in KIP-601
> # Optimize the logic for NetworkClient.leastLoadedNode()
> Changes:
> # Added a new common client configuration parameter
> socket.connection.setup.timeout.ms to the NetworkClient. Handle potential
> transportation layer timeout using the same approach as it handling potential
> request timeout.
> # When no connected channel exists, leastLoadedNode() will now provide a
> disconnected node that has the least number of failed attempts.
> # ClusterConnectionStates will keep the connecting node ids. Now it also has
> several new public methods to provide per connection relavant data.
