> In a very busy authed cluster, renewing/caneling/getting delegation token get
> slow and it will slow down the speed of handling rpcs from client. Since
> AbstractDelegationTokenSecretManager is a thread-safe manager, we propose to
> change the fs lock from write lock to read lock(protect editlog rolling)
