Steps to reproduce: 1. Create a 2-node cluster 2. Create a new index 3. Add one doc to the index 4. Take cluster down using Nodes Shutdown API 5. Change cluster.name in elasticsearch.yml on both nodes 6. service elasticsearch start on both nodes 7. Cluster comes up OK, looks like working cluster in BigDesk 8. Queries against your previously-working index return IndexMissingException And if I change the cluster name back to its original name and restart the cluster, the index works fine again. Is this a bug? Design limitation? Pilot error? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

If you want to rename a cluster you will have to modify that name also in /data dir. For example: mv ./data/elasticsearch ./data/mynewclustername On all nodes. -- David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs Le 22 mai 2013 à 20:58, Brian Gadoury [bgadoury@endpoint.com](mailto:bgadoury@endpoint.com) a écrit : > Steps to reproduce: > Create a 2-node cluster > Create a new index > Add one doc to the index > Take cluster down using Nodes Shutdown API > Change cluster.name in elasticsearch.yml on both nodes > service elasticsearch start on both nodes > Cluster comes up OK, looks like working cluster in BigDesk > Queries against your previously-working index return IndexMissingException > And if I change the cluster name back to its original name and restart the cluster, the index works fine again. > > Is this a bug?

Feature. The index data reside on disk in a path partially defined by the cluster name. Once you changed it, ES created a new folder structure. When you changed it back, it used the original data.
