What changes were proposed in this pull request?
The change updates RangerKrbFilter.createAuthCookie() to format the cookie Expires date with Locale.US, instead of relying on the JVM default locale. This prevents JDK 9+/CLDR locales such as en_GB from generating invalid HTTP cookie dates like Sept instead of Sep.
ASF Jira : https://issues.apache.org/jira/browse/RANGER-5836
How was this patch tested?
Added a new unit test for this particular change and also validated manually in a Kerberized Ranger setup in local docker with en_GB and September expiry: after the fix, hadoop.auth uses Sep and Java parses the cookie as valid.
