[ https://issues.apache.org/jira/browse/ZOOKEEPER-498?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Flavio Paiva Junqueira updated ZOOKEEPER-498: - Attachment: ZOOKEEPER-498.patch This patch includes documentation a reimplementation of HierarchicalQuorumTest. The new implementation of HierarchicalQuorumTest is based on QuorumBase, the main differences being that HQT uses hierarchical quorums and FLE for leader election. It uses testHammerBasic of ClientTest to verify that upon the election of a leader the ensemble works as expected. When I initially implemented the test, it was failing to terminate due to FLE failing to shutdown properly. I implemented some modifications to FLE to make sure that it shuts down correctly.

[jira] Updated: (ZOOKEEPER-498) Unending Leader Elections : WAN configuration
[ https://issues.apache.org/jira/browse/ZOOKEEPER-498?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Patrick Hunt updated ZOOKEEPER-498: --- Fix Version/s: 3.3.0 Assignee: Patrick Hunt Unending Leader Elections : WAN configuration - Key: ZOOKEEPER-498 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-498 Project: Zookeeper Issue Type: Bug Components: leaderElection Affects Versions: 3.2.0 Environment: Each machine: CentOS 5.2 64-bit 2GB ram java version 1.6.0_13 Java(TM) SE Runtime Environment (build 1.6.0_13-b03) Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02, mixed Network Topology: DC : central data center POD(N): remote data center Zookeeper Topology: Leaders may be elected only in DC (weight = 1) Only followers are elected in PODS (weight = 0) Reporter: Todd Greenwood-Geer Assignee: Patrick Hunt Priority: Critical Fix For: 3.2.1, 3.3.0 Attachments: dc-zook-logs-01.tar.gz, pod-zook-logs-01.tar.gz, zoo.cfg In a WAN configuration, ZooKeeper is endlessly electing, terminating, and re-electing a ZooKeeper leader. The WAN configuration involves two groups, a central DC group of ZK servers that have a voting weight = 1, and a group of servers in remote pods with a voting weight of 0. What we expect to see is leaders elected only in the DC, and the pods to contain only followers. What we are seeing is a continuous cycling of leaders.
