Summary: System Tests for Unclean Recovery
Key: KAFKA-18720
URL: https://issues.apache.org/jira/browse/KAFKA-18720
Project: Kafka
Issue Type: Sub-task
Reporter: Jonah Hooper
Assignee: Jonah Hooper
There should be significant system-tests for unclean elections in order to
prevent regressions. We should build a test for each new strategy. The tests
will need to shutdown brokers in a specific configuration, deliberately mess
with their logs and then restart them given a specific recovery election
strategy.
We will need separate tests for:
1. Balanced strategy
2. Designated election
3. Aggressive strategy
4. No strategy (IE wait for administrator)
System tests which discover whether or not the controller automatically detects
scenarios which warrant unclean election may also need to be tested if they
cannot be fully covered by a unit or integration test.
