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.
