> When hiveserver2 is behind multiple proxies there is possibility of "broken
> pipe", "connect timeout" and "read timeout" exceptions if one of the
> intermediate proxies or load balancers decided to reset the underlying tcp
> socket after idle timeout. When the connection is broken and when the query
> is submitted after idle timeout from beeline (or client) perspective the
> connection is open but http methods (POST/GET) fails with socket related
> exceptions. Since these methods are not sent to the server these are safe for
> client side retries.
>
> Also HIVE-12371 seems to apply the socket timeout only to binary transport.
> Same can be passed on to http client as well to avoid retry hang issues with
> infinite timeouts.
