PH28811: THE KAFKA ADAPTER LISTENER IS UNABLE TO RECOVER WHEN THE KAFKA BROKER'S INTERVAL TIME HAS EXPIRED DURING MAP PROCESSING

APAR status

• Closed as program error.

Error description

• The Kafka Adapter listener is unable to recover whenever the
  Kafka broker's interval time (as set in max.poll.interval.ms)
  has expired during map processing.
  

Local fix

• ITXCQ - ITX00060263
  GM / GM
  Circumvention: Adjusting the max.poll.interval.ms setting to a
  larger value may avoid the problem.
  

Problem summary

• Users Affected:
  IBM Transformation Extender users using Apache Kafka adapter.
  
  Problem Description:
  The adapter was not handling the scenario where it was consuming
  messages as member of a consumer group, and the time between the
  last poll() and the offset commit was longer than the time
  specified in max.poll.interval.ms configuration setting, causing
  the broker to perform partition rebalancing and the offset
  commit operation to fail. The adapter was not able to recover
  from this event and to resume consuming messages.
  
  Platforms Affected:
  All
  

Problem conclusion

• New commands were added to the Kafka adapter to assist with
  handling offset commit failures that can occur after partition
  rebalancing took place.
