Gwen Shapira commented on KAFKA-1811: ------------------------------------- Few notes that may help: 1. We like reviewing with review board. Here's a friendly instruction page on how to add the patch to JIRA and RB at once: https://cwiki.apache.org/confluence/display/KAFKA/Kafka+patch+review+tool 2. We also like unit tests :) 3. I'd consider pushing this check down to registerBrokerInZk. It seems like a natural place to ensure uniqueness of registered brokers before registering. 4. Another thing to consider is race conditions - what if new broker registers while we are checking? Perhaps we can even use ZK itself to enforce uniqueness? (Note: I'm not a committer, so those suggestions are not binding. just ideas for improvements) > ensuring registered broker host:port is unique > ---------------------------------------------- > > Key: KAFKA-1811 > URL: https://issues.apache.org/jira/browse/KAFKA-1811 > Project: Kafka > Issue Type: Improvement > Reporter: Jun Rao > Labels: newbie > Attachments: KAFKA_1811.patch > > > Currently, we expect each of the registered broker to have a unique host:port > pair.
