we are using spark processing to load data to elastic search. we are using elastic cloud and our spark elastic search connection as below:

\<  
val conf = new SparkConf().setAppName("loaduserdata").setMaster("local")  
.set("es.index.auto.create", "true")  
.set("es.nodes","[xxxx.eu-west-1.aws.found.io](http://xxxx.eu-west-1.aws.found.io)")  
.set("es.port","9243")  
.set("es.net.http.auth.user","xxx")  
.set("es.net.http.auth.pass","xxx")  
.set("es.nodes.wan.only","false")  
/\>  
Getting below Error

//
