--------------------------------------
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.
