Hi All, Is there any opportunity to run multiple instances or multiple nodes of elasticsearch in the same machine. I am getting below on running below command. start "ElasticSearch1" /I "cmd" "D:\SWTOOLS\Apache\Servers\elasticsearch-5.4.0\bin\elasticsearch.bat -Des.config=%ES\_HOME%/config/elasticsearch1.yml" Error :: [2017-08-08T16:21:34,753][INFO][o.e.n.Node] [01hw791865-node-1] initializing ...

For testing? Just run: ```auto bin/elasticsearch ``` and then ```auto bin/elasticsearch ``` in another terminal. Should work OOTB. If you really need to change some settings, you can pass them using the command line like `-Enode.name=node1` or creating a dir `config1` and `config2` and use `-Epath.conf=config1` and `-Epath.conf=config2`. Don't forget to copy all the config files in each config dir. ---
