RestClient instances should receive a `close()`call at the end of their lifecyle, as documented here. [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-low-usage-initialization.html] We have monitored file descriptor leaks on systems running Apache Drill and found that they are associated with Drill's ElasticSearch plugin, and that in turn makes use of Calcite's ElasticSearch adapter. -- This message was sent by Atlassian Jira (v8.20.1#820001)
