Gergely Farkas created HIVE-27866:
-------------------------------------
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:
