[jira] [Created] (SAMZA-168) Getting Kafka system metadata should back off on retry

Martin Kleppmann created SAMZA-168:
--------------------------------------

             Summary: Getting Kafka system metadata should back off on retry
                 Key: SAMZA-168
                 URL: https://issues.apache.org/jira/browse/SAMZA-168
             Project: Samza
          Issue Type: Bug
    Affects Versions: 0.6.0
            Reporter: Martin Kleppmann
            Assignee: Martin Kleppmann
             Fix For: 0.7.0


If an exception occurs in KafkaSystemAdmin.getSystemStreamMetadata (eg because the broker returns an error for the partitions metadata request), we currently retry in a tight loop. This puts unnecessary load on Kafka, and especially risks hammering Zookeeper.

There should be an exponential back-off in the retry loop.
