m1a2st opened a new pull request, #23348: URL: https://github.com/apache/kafka/pull/23348
Follow-up to (#23227). Before bootstrap DNS resolution completes, `coordinatorRequestManager.coordinator()` is empty, causing the coordinator-unknown path in `maximumTimeToWait()` to return `heartbeatRequestState.heartbeatIntervalMs()`. However, the heartbeat interval is initialized to 0 and is not updated until the first heartbeat response is received. As a result, a member in the JOINING state reports `maximumTimeToWait() == 0`. Since the application thread's poll timeout is bounded by this value, both the application and network threads can busy-spin until the coordinator is discovered. -- This is an automated message from the Apache Git Service.
