------------------------------------------
Summary: HiveServer2 should not log errors when clients issue
connection reset
Key: HIVE-18964
URL: https://issues.apache.org/jira/browse/HIVE-18964
Project: Hive
Issue Type: Improvement
Components: HiveServer2
Affects Versions: 2.3.2, 3.0.0
Reporter: Vihang Karajgaonkar
Assignee: Vihang Karajgaonkar
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.
