[jira] [Created] (IMPALA-12093) impala-shell should preserve all cookies by default
Joe McDonnell created IMPALA-12093:
--------------------------------------
Summary: impala-shell should preserve all cookies by default
Key: IMPALA-12093
URL: https://issues.apache.org/jira/browse/IMPALA-12093
Project: IMPALA
Issue Type: Improvement
Components: Clients
Affects Versions: Impala 4.3.0
Reporter: Joe McDonnell
Currently, impala-shell's http_cookie_names parameter specifies which cookies should be preserved and sent back with subsequent requests. This defaults to a couple well-known cookie names that Impala uses.
In general, we don't know what proxies are between impala-shell and Impala, and we don't know what cookie name they rely on being preserved. As an example, Apache Knox can rely on a cookie it sets to route requests to the appropriate Impala coordinator. Limiting our cookie preservation to a small allow list makes this much more brittle and hard to use. Clients need to know the right list of cookies to put in http_cookie_names, and that is not obvious.
It seems like the default behavior should be to preserve all cookies. We can keep a way to disallow or limit the cookies for unusual cases.
