             Summary: Implement token storage solution based on MySQL
                 Key: HADOOP-18535
                 URL: https://issues.apache.org/jira/browse/HADOOP-18535
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Hector Sandoval Chaverri
            Assignee: Hector Sandoval Chaverri


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.
