Hi all, I tried to connect my Spark code with Elastic Cloud without success. Following this post [https://www.elastic.co/guide/en/cloud/current/shield.html](https://www.elastic.co/guide/en/cloud/current/shield.html), I have a configuration as follow: es.http.timeout=5m es.index.auto.create=true es.net.http.auth.pass= mypass es.net.http.auth.user= myuser es.net.ssl=true es.net.ssl.cert.allow.self.signed=true es.net.ssl.protocol=true es.nodes=46\*\*\*\*.us-east-1.aws.found.io es.nodes.wan.only=true es.port=9343 es.scroll.size=50 - Im using Spark 1.6.0, trial version of Elastic Cloud - Elasticsearch 2.2.0, es-hadoop connector elasticsearch-spark\_2.10-2.2.0-rc1 =\> with this setup I can connect to AWS Elasticsearch cluster ( without authentication). - Here is the error with above configuration: org.elasticsearch.hadoop.EsHadoopIllegalStateException: Cannot instantiate SSL - Here is the error without SSL enable: org.elasticsearch.hadoop.rest.EsHadoopNoNodesLeftException: Connection error (check network and/or proxy settings)- all nodes failed; tried [[23.23.98.74:9343]] - I have tried with different port: 9200, 9243, 9343, 80, 443 with and without SSL enable but cannot connect. Could you please point out the configuration to connect from Spark to Elastic Cloud with Shield. Any help is appreciate !! ---

> [@Pham\_Khanh](#): > > es.net.ssl.protocol=true Where do folks come up with this setting? It's the second time this month and I have no idea where folks copy this incorrect configuration; in case the name is not clear enough, the docs clearly [state](https://www.elastic.co/guide/en/elasticsearch/hadoop/current/configuration.html#_ssl): > SSL protocol to be used "true" is not a valid protocol - anything wrong with the default "TLS"? Instead of overriding the defaults (`es.scroll.size` or the timeout), reading the docs and only configuring the nodes and _maybe_ the port is a much better time investment,. ---

Thanks a lot for your help, Costin ! I have kept the es.net.ssl.protocol as default and tried with different port configurations : 9200, 9243, 9343, 443, 80 with no success. I have read through :[Apache Hadoop with Shield](https://www.elastic.co/guide/en/shield/current/hadoop.html) , [es-hadoop configuration](https://www.elastic.co/guide/en/elasticsearch/hadoop/master/configuration.html) and [es-hadoop security](https://www.elastic.co/guide/en/elasticsearch/hadoop/current/security.html) but still cannot figure out what should be the right configuration 😕 . Tried to find in the documentation of Elastic Cloud as well but the closest configuration available is :[Java Transport Client](https://www.elastic.co/guide/en/cloud/current/shield.html#shield-transport) . Do u have any experience connecting es-hadoop with Elastic Cloud ( Found) or any configuration could be derive similarly to the Java Transport Client ? ---

What is the error that you are getting? And what is your ES-Cloud configuration? If you need help with the cloud setup, I recommend the dedicated forum [here](https://discuss.elastic.co/c/cloud). ---
