-------------------------------------

             Summary: JDBC: HttpRequestInterceptorBase should not add an empty "Cookie:" header to the request if no custom cookies have been specified
                 Key: HIVE-27866
                 URL: https://issues.apache.org/jira/browse/HIVE-27866
             Project: Hive
          Issue Type: Bug
          Components: JDBC
    Affects Versions: 4.0.0-beta-1
            Reporter: Gergely Farkas
            Assignee: Gergely Farkas


While debugging session cookies of a sticky session, I noticed that the JDBC driver adds an empty "Cookie" header to the request if no custom cookie is configured. This is both unnecessary and unfortunately intermittently interferes with the sticky session handling in the kubernetes nginx ingress controller, so I created this ticket to omit the empty "Cookie" header.

some logs from the debug session:
