--------------------------------------------
Summary: Reconfig Causes Inconsistent Configuration file among the
nodes
Key: ZOOKEEPER-2865
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2865
Project: ZooKeeper
Issue Type: Bug
Components: leaderElection, quorum, server
Affects Versions: 3.5.3
Reporter: Jeffrey F. Lukman
When we run our Distributed system Model Checking (DMCK) in ZooKeeper v3.5.3
by following the workload in ZK-2778:
- initially start 2 ZooKeeper nodes
- start 3 new nodes
- do a reconfiguration (the complete reconfiguration is attached in the
document)
We think our DMCK found this following bug:
- while one of the just joined nodes has not received the latest configuration
update ~ called as node X ~ the initial leader node closed its port, therefore
causing the node X to be isolated.
For complete information of the bug, please see the document that is attached.
