Hello all, My question is about clusters and plugins. I have ES in cluster (a master with two slaves) with a plugin in order to load data in it. Doing testing I have installed this plugin into the three ES instances. Is it the right way ?? Can I indicate that only one instance executes the plugin (master or slave) ??? Thanks for all.

Hey, this is the right way, if you are using plugins, which load java code, you should enable it on all of your nodes. Apart from that, the plugin should make sure, that its functionality is only executed once. This depends highly on the plugin, but it is quite simple to make sure, that some code is only executed on the master node for example. Can you talk about your plugin, so we might be able to help you more specific. --Alex On Thu, May 23, 2013 at 3:39 PM, Carlos Soria [soriacorado@gmail.com](mailto:soriacorado@gmail.com) wrote: > Hello all, > > My question is about clusters and plugins.

Hello again, It's a java plugin that loads data from an Informix data base to ES, in an incremental way, based in a timestamp stored into ES also, very similar to the JDBC river example. ES is a great solution that is bringing me much too good at my job, thanks. Thank you very much for responding so quickly... Regards, Carlos Soria.

Hi Carlos, its right... plugins should be there, I recon you to use ES documents directly to save plugins configuration file to have all sync, otherwise a change in one has to be done in the others... maybe there is some notification between nodes... I have to dig more in the source code but to save this situation I had to use es to save the plugin configuration El jueves, 23 de mayo de 2013 15:39:21 UTC+2, Carlos Soria escribió: > Hello all, > > My question is about clusters and plugins.

A river plugin is meant to be run only on one node in the cluster. If that node leaves the cluster, the cluster will start on another node. As long as your plugin is a river plugin, you should be fine. -- Ivan On Fri, May 24, 2013 at 7:28 AM, Carlos Soria [soriacorado@gmail.com](mailto:soriacorado@gmail.com) wrote: > Muchas gracias/Th > > El jueves, 23 de mayo de 2013 15:39:21 UTC+2, Carlos Soria escribió: > > > Hello all, > > > > My question is about clusters and plugins.
