What do the proper way to get the localnode (and it's id) in a plugin? I have tried many ways and it always seems to be null. The node just started and is loading the data from disk. Because of my inability to get localNodeId, I have had to fall back to using node.name for my lookups, but this seems more error prone. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Use something like this for node name public class MyService extends AbstractLifeCycleComponent { @Inject public MyService(Settings settings, Node node) { super(settings); String name = node.settings().get("name"); ... } and for node IDs public class MyService extends AbstractLifeCycleComponent { @Inject public MyService(Settings settings, ClusterService clusterService) { super(settings); String nodeId = clusterService.localNode().getId(); ... } Jörg On Fri, Mar 6, 2015 at 5:10 AM, Kadaan [jbaranick@gmail.com](mailto:jbaranick@gmail.com) wrote: > What do the proper way to get the localnode (and it's id) in a plugin?

Interesting. I was trying ((ClusterStateResponse)state).getState().nodes().localNode(), but this didn't work.

In ClusterStateRequest, you have to set clusterStateRequest.nodes(true) to get nodes returned.

Yes. I did that [ _clusterStateRequest.clear().nodes(true).routingTable(true)_ ], but I still wasn't able to get the localNodeId. It seems like the localNodeId is not set while the node is recovering.
