[jira] [Resolved] (KAFKA-4489) Kafka Consumer throws Java Heap Out
of Space Error on failed SSL connections
[ https://issues.apache.org/jira/browse/KAFKA-4489?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ismael Juma resolved KAFKA-4489.
--------------------------------
Resolution: Duplicate
The OOM is not intentional. It's just that the PLAINTEXT protocol assumes a message size at a particular point and doesn't do any verification. I filed KAFKA-4493 as a more generic issue regarding this.
Marking this as a duplicate of KAFKA-4491, which has a clearer description of the problem.
