Description

In the Elasticsearch6 connector, the RestClientFactory allows users to customize the RestClientBuilder. However, certain customizations like adding Sniffing
require access to the low-level rest client, which can be obtained through the high level rest client. The RestHighLevelClient is instantiated in the api call bridge, and is never exposed to the user.

To my knowledge, the current Elasticsearch6 connector does not utilize sniffing or provide a way to add it in. The Elasticsearch6 connector should expose some type of access to the RestHighLevelClient to allow for custom sniffing.
