Is it normal for a single node elasticsearch process to open 13 sockets to itself? This seems like an excessive zen disco party and inexplicable. I am trying out v1.4. Is it possible to set the transport protocol port? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

More info: I tried to set the transport port like this: -Dtransport.tcp.port=9999 on the elasticsearch command line, but it still uses port 9300.

ES uses a netty worker pool in order to be able to connect to multiples nodes. The size of the pool does not automatically take into consideration that you want a single node cluster only, it does not shrink or grow. You can reduce the size of the netty worker pool with the setting transport.netty.worker\_count Any command line parameter must be prefixed by "es." so you should use - Des.transport.tcp.port=9999 Jörg On Tue, Dec 16, 2014 at 11:08 PM, Paul Baclace [paul.baclace@gmail.com](mailto:paul.baclace@gmail.com) wrote: > More info: I tried to set the transport port like this: > -Dtransport.tcp.port=9999 on the elasticsearch command line, but it still > uses port 9300. > > On Tuesday, December 16, 2014 12:42:12 PM UTC-8, Paul Baclace wrote: > > > Is it normal for a single node elasticsearch process to open 13 sockets > > to itself?

Now that you pointed out the addition "es." prefix needed when specifying on the command line, I can see that: [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/setup-configuration.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/setup-configuration.html) shows it via color in an example and with "instead of". Apparently, that was not obvious enough for me! Thanks for the transport.netty.worker\_count tip. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
