If hftp cannot locate either a hdfs or hftp token in the ugi, it will call getDelegationToken to acquire one from the remote nn. This method may return a null Token if security is disabled on the remote nn. Hftp will internally call its setDelegationToken which will throw a NPE when the token is null.
Actually, if any problem happens while acquiring the token it assumes security is disabled! However, it's a pre-existing issue beyond the scope of the token renewal changes.
