Hi there. I'm building a plugin that as part of its initialization it creates an special index if one is not present. It seems though that the admin operations are still not ready by the time I have my plugin started. So I put this piece of code in one of the components of the plugin that is created by the plugin's module. Code can be found here: [https://gist.github.com/viniciusccarvalho/d27aa2b5aaf8dd8eb9d0](https://gist.github.com/viniciusccarvalho/d27aa2b5aaf8dd8eb9d0) If this is not the right place to create an index, where should I put this code? I did noticed that my plugin is started before other services in ES. Regards -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

ES starts all plugins before node startup and completion of recovery. Run your plugin in a separate thread, and wait for cluster state 'green' (or 'yellow') before creating an index.
