Matthias J. Sax updated KAFKA-5004: ----------------------------------- Affects Version/s: 0.10.2.0 > poll() timeout not enforced when connecting to 0.10.0 broker > ------------------------------------------------------------ > > Key: KAFKA-5004 > URL: https://issues.apache.org/jira/browse/KAFKA-5004 > Project: Kafka > Issue Type: Bug > Components: clients, consumer > Affects Versions: 0.10.2.0 > Reporter: Matthias J. Sax > > In 0.10.1, heartbeat thread and new poll timeout {{max.poll.interval.ms}} got > introduced via KIP-62. In 0.10.2, we added client-broker backward > compatibility. > Now, if a 0.10.2 client connects to a 0.10.0 broker, the broker only > understand the heartbeat timeout but not the poll timeout, while the client > is still using the heartbeat background threat. Thus, the new client config > {{max.poll.interval.ms}} is ignored. > In the worst case, the polling threat might die while the heartbeat thread is > still up. Thus, the broker would not timeout the client and no rebalance > would be triggered while at the same time the client is effectively dead not > making any progress in its assigned partitions. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
