------------------------------------

             Summary: ElasticSearchClientImpl should allow configuration of useful Elasticsearch RestClient options
                 Key: NIFI-10797
                 URL: https://issues.apache.org/jira/browse/NIFI-10797
             Project: Apache NiFi
          Issue Type: Improvement
    Affects Versions: 1.18.0
            Reporter: Chris Sampson


The ElasticSearchClientImpl Controller Service should expose and make use of useful [Elasticsearch RestClient|https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.13/java-rest-low.html] configuration options, such as:

* [Sniffer|https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.13/_usage.html]
** Sniff on connect
** Sniff on failure
* Compression
* Node Selection: {{Any}} or {{Skip Dedicated Master}}

The documentation for this controller should probably also indicate that it is using version {{7.13.4}} of the Elasticsearch low-level Rest Client library so as to remain open source and avoid the library's validation of connections being made to Elastic-based services (i.e. the current setup within NiFi *should* allow users to connect with Elasticsearch alternatives, such as AWS OpenSearch).
