[jira] [Created] (KAFKA-902) Randomize backoff on the clients for metadata requests

Neha Narkhede created KAFKA-902:
-----------------------------------

             Summary: Randomize backoff on the clients for metadata requests
                 Key: KAFKA-902
                 URL: https://issues.apache.org/jira/browse/KAFKA-902
             Project: Kafka
          Issue Type: Bug
          Components: replication
    Affects Versions: 0.8
            Reporter: Neha Narkhede
            Assignee: Neha Narkhede
            Priority: Critical


If a Kafka broker dies and there are a large number of clients talking to the Kafka cluster, each of the clients can end up shooting metadata requests at around the same time. It is better to randomize the backoff on the clients so the metadata requests are more evenly spread out
