titan-server-cassandra-es.properties shows how to set up Titan Server's ElasticSearch to accept remote connections (local-mode=false allows remote connections on port 9300). Main.scala shows how to configure TitanGraph to use the Titan Server's ElasticSearch.
val conf = new BaseConfiguration()
conf.setProperty("storage.backend","cassandra")
conf.setProperty("storage.hostname","127.0.0.1")
conf.setProperty("storage.index.search.backend", "elasticsearch")
conf.setProperty("storage.index.search.hostname", "127.0.0.1")
val graph = TitanFactory.open(conf)
