> 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 has been created, based on MySQL, to handle a higher number of
> writes.
> We measured the throughput of each token operation (create/renew/cancel) on
> different setups and obtained the following results:
> # Sending requests directly to Namenode (no RBF):
> Token creations: 290 reqs per sec
> Token renewals: 86 reqs per sec
> Token cancellations: 97 reqs per sec
> # Sending requests to routers using Zookeeper based secret manager:
> Token creations: 31 reqs per sec
> Token renewals: 29 reqs per sec
> Token cancellations: 40 reqs per sec
> # Sending requests to routers using SQL based secret manager:
> Token creations: 241 reqs per sec
> Token renewals: 103 reqs per sec
> Token cancellations: 114 reqs per sec
> We noticed a significant improvement when using a SQL secret manager,
> comparable to the throughput offered by Namenodes.
