LuciferYang opened a new pull request, #14408: URL: https://github.com/apache/gravitino/pull/14408
### What changes were proposed in this pull request? When impersonation is disabled, `ClosableHiveCatalog.doKerberosOperations` runs the operation as the Kerberos login user without requesting a delegation token, as `ClosableJdbcCatalog` already does through `KerberosCatalogUtils.doKerberosOperations`. The impersonation path is unchanged. ### Why are the changes needed? All requests share the login UGI, so it must not carry any caller's token. Operations that run as the login user do not need the token either. Fix: #14406 ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? New `TestClosableHiveCatalog`: without impersonation, no token is requested and the login UGI holds no token; with impersonation, the token is requested for the proxied principal and lands on the proxy UGI only. -- This is an automated message from the Apache Git Service.
