Ray Chiang updated KAFKA-3468:
------------------------------
Component/s: clients
> Java clients never fail when bootstrap uses incorrect port
> ----------------------------------------------------------
>
> Key: KAFKA-3468
> URL: https://issues.apache.org/jira/browse/KAFKA-3468
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Reporter: Grant Henke
> Priority: Major
>
> When a client bootstrap uses a valid host but an incorrect port, the java
> clients will never fail but instead loop forever trying to fetch metadata. A
> sample debug log of the consumer is:
> {noformat}

> metadata request (org.apache.kafka.clients.NetworkClient:629)
> [2016-03-25 11:37:39,880] DEBUG Initiating connection to node -1 at
> localhost:9999. (org.apache.kafka.clients.NetworkClient:492)
