> 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.
