--------------------------------------
Summary: No reconsiliation after partitioning
Key: KAFKA-3206
URL: https://issues.apache.org/jira/browse/KAFKA-3206
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.9.0.0
Reporter: Arkadiusz Firus
Kafka topic partition could be in an inconsistent state where two nodes see
different partition state.
Steps to reproduce the problem:
1. Create topic with one partition and replication factor 2
2. Stop one of the Kafka nodes where that partition resides
3. Send following messages to that topic:
ABC
BCD
CDE
3. Stop the other Kafka node
Currently none of the nodes should be running
4. Start first Kafka node - this node has no records
5. Send following records to the topic:
123
234
345
6. Start the other Kafka node
The reconciliation should happen here but it does not.
7. When you read the topic you will see
123
234
345
8. When you stop the first node and read the topic you will see
ABC
BCD
CDE
This means that the partition is in inconsistent state.
