> HiveServer2 logs an ugly exception trace when clients issue a connection reset. There is nothing we can do when the connection is reset. This exception trace should either be ignored or logged only in debug mode.
> Things become worse if you are using load balancer like HAProxy which has its own health checks. HAProxy issues a connection reset to "quickly" close the connection once it finds that HS2 is up and available. This spams the logs at a very high frequency and makes them unusable for debugging purposes.
