Announcing Apache Kafka 0.9.0.1 and Confluent Platform 2.0.1

A few months ago, we announced the major release of Apache Kafka 0.9, which added several new features like Sécurité, Kafka Connect, the new Java consumer and also critical bug fixes. Today, I am pleased to announce the availability of the first patch release of the Kafka 0.9 series: the 0.9.0.1 release of Apache Kafka and the corresponding patch release of the Plateforme Confluent 2.0.1. The 0.9.0.1 release fixes a total of 68 issues, out which 45 are bug fixes and 20 are general improvements.

We recommend all users upgrade to this release by bumping up the version of your Kafka dependencies to 0.9.0.1 (Confluent Platform users: 0.9.0.1-cp1) in your applications and updating the binary installations on server machines.

Here is a quick overview of the notable Kafka-related bug fixes in the release, grouped by the affected functionality. You can review the complete list of issues fixed in the release notes.

New Java consumer

  • KAFKA-2978: Topic partition is not sometimes consumed after rebalancing of consumer group
  • KAFKA-3179: Kafka consumer delivers message whose offset is earlier than sought offset.
  • KAFKA-3157: Mirror maker doesn’t commit offset with new consumer when there is no more messages    
  • KAFKA-3170: Default value of fetch_min_bytes in new consumer is 1024 while doc says it is 1

Compatibility

  • KAFKA-2695: Handle null string/bytes protocol primitives
  • KAFKA-3100: Broker.createBroker should work if json is version > 2, but still compatible
  • KAFKA-3012: Avoid reserved.broker.max.id collisions on upgrade

Sécurité

  • KAFKA-3198: Ticket Renewal Thread exits prematurely due to inverted comparison
  • KAFKA-3152: kafka-acl doesn’t allow space in principal name
  • KAFKA-3169: Kafka broker throws OutOfMemory error with invalid SASL packet
  • KAFKA-2878: Kafka broker throws OutOfMemory exception with invalid join group request
  • KAFKA-3166: Disable SSL client authentication for SASL_SSL security protocol

Performance/memory usage

  • KAFKA-3003: The fetch.wait.max.ms is not honored when new log segment rolled for low volume topics
  • KAFKA-3159: Kafka consumer 0.9.0.0 client poll is very CPU intensive under certain conditions
  • KAFKA-2988: Change default configuration of the log cleaner
