URL: https://issues.apache.org/jira/browse/HADOOP-17416
Project: Hadoop Common
Issue Type: Improvement

Reporter: Ahmed Hussein
Reducing synchronization in the ZK secret manager is complicated by excessive
and unnecessary global synchronization in the
AbstractDelegationTokenSecretManager. All RPC services, not just the KMS, will
benefit from the reduced synchronization.
