> We have seen some issues around TokenCache getDelegationToken failures even
> though the UGI already has a valid token. The tricky part is the token map is
> keyed by the canonical service name, which can be different from the actual
> service field in the token, e.g. KMS token in HA case. The current UGI log
> dumps all the tokens but not the keys of the token map. This ticket is opened
> to include the complete token map information in the debug log.
