KAFKA-19521: Fix consumption and leaving group when source topic is deleted
(#20735)
Integration tests expecting `MissingSourceTopicException` were timing
out and taking 5+ minutes because [PR
#20284](https://github.com/apache/kafka/pull/20284) set the missing
topics timeout to `max.poll.interval.ms` (default 300 seconds).
This is inappropriate because:
- When source topics don't exist, actual poll frequency is `poll.ms`
(100ms), not `max.poll.interval.ms`
- The exception should be raised much faster based on heartbeat
frequency
## Solution
Use `2 * heartbeatIntervalMs` (from broker via KIP-1071) as the timeout
instead:
- Ensures at least one heartbeat is sent before raising the exception
- Falls back to `max.poll.interval.ms` for backward compatibility
- Fixes slow integration tests
## Changes
1. Track `heartbeatIntervalMs` in `StreamsRebalanceData` and update it
on each heartbeat response
2. Use `2 * heartbeatIntervalMs` as timeout in
`StreamThread.handleMissingSourceTopicsWithTimeout()`
3. Update `HandlingSourceTopicDeletionIntegrationTest` to test both
"classic" and "streams" protocols
4. Update `StreamsRebalanceDataTest`,
`StreamsGroupHeartbeatRequestManagerTest` and `StreamThreadTest` to test
`StreamsRebalanceData` and its behaviour
