[NoHttpResponseException](https://hc.apache.org/httpclient-legacy/exception-handling.html)
> In some circumstances, usually when under heavy load, the web server may
be able to receive requests but unable to process them. A lack of sufficient
resources like worker threads is a good example. This may cause the server to
drop the connection to the client without giving any response. HttpClient
throws NoHttpResponseException when it encounters such a condition. In most
cases it is safe to retry a method that failed with NoHttpResponseException.
In case of Kyuubi Server is overloaded and does not have enough resources to
allocate threads to handle the corresponding request, the request will be
dropped and no response will be returned, Kyuubi Rest Client should catch this
exception and retry.
