Hi Everyone, i trying to connect hive with elasticsearch using the ES-Hadoop Connector but i receive this error: "java.sql.SQLException: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. org.elasticsearch.hadoop.EsHadoopIllegalArgumentException: Cannot detect ES version - typically this happens if the network/Elasticsearch cluster is not accessible or when targeting a WAN/Cloud instance without the proper setting 'es.nodes.wan.only'" thank you ---

This often happens if your Hive nodes cannot communicate with your ES nodes. You will need to recheck your connections. ---
