Hello, I'm trying to bring a second node into my cluster. I've set it up as unicast and the two nodes are trying to communicate however, they claim they're incompatible versions. Node One: > { > "ok" : true, > "status" : 200, > "name" : "ES Server Node", > "version" : { > "number" : "0.90.11", > "build\_hash" : "11da1bacf39cec400fd97581668acb2c5450516c", > "build\_timestamp" : "2014-02-03T15:27:39Z", > "build\_snapshot" : false, > "lucene\_version" : "4.6" > }, > "tagline" : "You Know, for Search" > } Node Two: > { > "ok" : true, > "status" : 200, > "name" : "Front End Server", > "version" : { > "number" : "0.90.11", > "build\_hash" : "11da1bacf39cec400fd97581668acb2c5450516c", > "build\_timestamp" : "2014-02-03T15:27:39Z", > "build\_snapshot" : false, > "lucene\_version" : "4.6" > }, > "tagline" : "You Know, for Search" > } As you can see, the version and build hash are identical, but I'm still getting this error: > Caught exception while handling

Just a guess, can you check also that you have the same exact Java versions across all nodes? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
