While reading about the different configuration options in https://www.elastic.co/guide/en/elasticsearch/hadoop/5.6/configuration.html I came around the options
es.nodes.wan.only . While they seem to be doing somethings similar, disabling the discovery of new nodes not included in
es.nodes.wan.only is said to highly impact the systems performance.
es.discovery.nodes also impacting the performance negatively, when
es.nodes has all the elastic nodes defined?
What are the differences between one parameter and the other?
This is a repost of a question I asked in stackoverflow, but that I got no response, so I was hoping that I would get an answer here.
