[GitHub] [kafka] Hangleton opened a new pull request, #13558: [KAFKA-14845] Implement test case simulating broker registration failure with Zookeeper when a session id is lost

[via GitHub]

Hangleton opened a new pull request, #13558:
URL: https://github.com/apache/kafka/pull/13558

   This PR implements the test case for 
[KAFKA-14845](https://issues.apache.org/jira/browse/KAFKA-14845). This test 
simulates the loss of a session ID with Zookeeper (for instance due to network 
partition) while a broker is in the process of creating its ephemeral znode 
under /brokers/ids/. This can result in broker registration failing with due to 
a `NODEEXISTS` error which is not handled by the fix 
[KAFKA-6584](https://issues.apache.org/jira/browse/KAFKA-6584) because in this 
case, the ID of the session of the conflicting ephemeral znode is not known by 
the broker.
   
   The corresponding timeline of events exercised by this test is reproduced 
below.
   
   A fix will be proposed in a separate PR.
