James Turton updated CALCITE-4992:
----------------------------------
Description:
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
have come to believe (but not proven) that they are associated with Drill's
ElasticSearch plugin, and that in turn makes use of Calcite's ElasticSearch
adapter.
