Good morning Does anyone have 2 or more instances running Elastic Search on the same machine? Problems who live 2 instances of Elastic Search in the same machine? Besides that would have to share the RAM, and consultation would be slower. A greeting and thanks -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Lots of people do, by either running two processes manually managed, or using container technology like Docker. Obviously you'd increase your management overhead, but I haven't heard any major issues from others using these methods.

I have 2 instances in one server, but none of them are data node, one is master (-Des.node.master=true -Des.node.data=false) and another is use for search balance (-Des.node.master=false -Des.node.data=false), totally fine, no load at all. But if these are data nodes, you probable shouldn't do that, better be one instance per machine.

I understand that you do not have two elasticsearch both operating, which have no problems with RAM or problems slow queries. In my case I need to install two elasticsearch in the same machine, and not know it would cause me problems in the short and long term. For example had thought about playing with the parameters of the RAM and Cache, but not if I could play some more parameter, so that the coexistence of both elastic was the best. Thank you.
