When running e2e test TestDbPrivilegeCleanupOnDrop.testRenameTablesWithinDBSinglePrivilege, I found the request received in SentryPolicyStoreProcessor.sentry_notify_hms_event is null
There are multiple issues in fix from "
SENTRY-2243: Extend the thrift definition for policy service to learn owner information"
1. The exception was thrown because the protocol_version was not set
2. TSentryAuthorizable.server was not set
3. TSentryHmsEventNotification.ownerType and ownerName are not set for table rename event
As a result, the request received by server is null since thrift at server side cannot re-construct a valid request of type TSentryHmsEventNotification
Once we fix the above issues, we need to make sure SentryPolicyStoreProcessor.sentry_notify_hms_event does not transfer owner in "alter table rename" event.
