Hi , We want to upgrade our Elasticsearch Servers to the latest Version of Es 1.4.2 , but we don't want to upgrade our Es java client to 1.4.2 (It's current version is 1.4.1). Will we have a Compatibility issue ? or we can proceed ? Thanks, Costya. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
