Borja Bravo Alférez created CURATOR-444:
-------------------------------------------
Summary: Two leader machines simultaneously after blocking one
zookeper network
Key: CURATOR-444
URL: https://issues.apache.org/jira/browse/CURATOR-444
Project: Apache Curator
Issue Type: Bug
Components: Recipes
Affects Versions: 4.0.0, 2.12.0
Environment: Linux
Reporter: Borja Bravo Alférez
Priority: Critical
Attachments: blockZookeeperPort.sh
How to reproduce de error:
- 3 Zookeeper nodes.
- Using LeaderLatch recipe with a listener.
- We block the zookeeper network with the attached script. It blocks
communication between zookeepers. Note that comunication is lost only for 10
seconds that is exactly our default session timeout.
Our curator configuration:
- Base sleep 100ms
- Max sleep 5000ms
- Default connection timeout 15000ms
- Default Session timeout 10000ms
I am working with a pull request. Fix seems trivial but creating the test not
so much.
