             Summary: Add metrics for KMS client and server encrypted key caches
                 Key: HADOOP-10802
                 URL: https://issues.apache.org/jira/browse/HADOOP-10802
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 3.0.0
            Reporter: Andrew Wang
            Assignee: Arun Suresh


HADOOP-10720 is adding KMS server and client caches for encrypted keys for performance reasons. It would be good to add metrics to make sure that the cache is working as expected, and to inform future dynamic cache sizing and refilling policies.
