> Hadoop RBF supports custom implementations of secret managers. At the moment,
> the only available implementation is ZKDelegationTokenSecretManagerImpl,
> which stores tokens and delegation keys in Zookeeper.
> During our investigation, we found that the performance of routers is limited
> by the writes to the Zookeeper token store, which impacts requests for token
> creation, renewal and cancellation. An alternative secret manager
> implementation will be made available, based on MySQL, to handle a higher
> number of writes.
